A stunning night in Sutherland!

Summer's well on its way so we've had a few really gorgeous nights during the past week!  While observing dwarf novae in the Large Magellanic Cloud last night, Petri & Fred snagged a set of images through 3 of the Sloan filters (u, g & r).  Combining these has produced one of SALT's most beautiful colour-composite images to date.  The combination of 1" seeing & a freshly stacked primary shows what the telescope's capable of under good conditions.  If only Darragh could see this kind of image quality!

SALT Status update for October 2015


Recent Scientific Papers
========================

The 2015 calendar year will top the number of 31 refereed SALT publications from 2014.  While waiting for the final tally, here is a list of SALT papers that have appeared since our last update in July:

* Brosch et al. study an "empty ring galaxy" using RSS/Fabry-Perot observations finding a past merger of disc galaxies and current star formation in a regularly spinning gas ring.  http://adsabs.harvard.edu/abs/2015MNRAS.451.4114B

* Coe & Kirk present a catalogue of Be/X-ray binary systems in the Small Magellanic Cloud including H-alpha measurement using RSS. http://adsabs.harvard.edu/abs/2015MNRAS.452..969C

* Hajduk et al. combine X-Shooter spectra with RSS data to conclude that [JD2002]11 is the ninth symbiotic star known in total, and only the 2nd known dusty symbiotic star in the Small Magellanic Cloud. http://adsabs.harvard.edu/abs/2015AcA....65..139H

* Karachentsev, Kniazev & Sharina present RSS spectroscopy of a globular cluster in the center of the nearby isolated dwarf spheroidal galaxy KKs3. http://adsabs.harvard.edu/abs/2015AN....336..707K

* Katkov, Kniazev & Sil'chenko show, using RSS spectra of isolated lenticular galaxies, that there is a large range in their formation epochs and that their gas is likely externally accreted by minor mergers. http://adsabs.harvard.edu/abs/2015AJ....150...24K

* Macfarlane et al. present the overview and first results of the large OmegaWhite survey at ESO/VST for short-period variable stars, including follow-up spectroscopy with SALT/RSS. http://adsabs.harvard.edu/abs/2015MNRAS.454..507M

* Menzies, Whitelock & Feast study AGB variables in the Local Group galaxy IC 1613 and their RSS spectra demonstrates on-going "hot bottom burning" in an Oxygen-rich Mira variable. http://adsabs.harvard.edu/abs/2015MNRAS.452..910M

* Silverman et al. include RSS data in their study of high-velocity features of calcium and silicon in a large sample of Type Ia SN spectra. http://adsabs.harvard.edu/abs/2015MNRAS.451.1973S

* Zinchenko et al. present oxygen abundance distributions in six late-type galaxies based on RSS spectra of regions of ionized hydrogen in these galaxies. http://adsabs.harvard.edu/abs/2015A%26A...582A..35Z

Too Large A Black Hole in the news
==================================

And in another new publication, Jacco van Loon from Keele University and Anne Sansom from the University of Central Lancashire used SALT to study a significantly over-sized nuclear black hole in a modest-mass early-type galaxy.   This result was featured on CNN along with the Espresso morning TV show here in South Africa.  For more details, see:
 On ADS: http://adsabs.harvard.edu/abs/2015MNRAS.453.2341V
 SALT Press Release:  http://www.salt.ac.za/news/too-large-a-black-hole/
 CNN:  http://edition.cnn.com/2015/09/26/world/black-hole-is-30-times-expected-size/index.html


Record number of Blocks Observed
================================

We don't know what the final number will be yet, but this semester has seen a record number of blocks observed!   Eric Depagne and Thea Koen passed the old record of 798 blocks on 3 October.  See how they celebrated the accomplishment of passing 800 observed blocks!

Laser Frequency Comb at SALT
============================

We have been fortunate to be approached by researchers from the University Heriot-Watt in Edinburgh, the Department of Photonics and Quantum Science, asking SALT to provide an on-sky test for their prototype laser frequency comb. These instruments provide an incredibly precise method to calibrate spectroscopy using tens of thousands of lines with well known wavelengths.  Currently, only HARPS at ESO is equipped with such an instrument, and with such a calibrator it regularly delivers precision down to a few cm/s.

The frequency comb is expected to be installed on the telescope for a three month period and provide HRS with a high stability calibration source. It will be installed, commissioned and tested as soon as it arrives in January 2016, and will be available for HRS science during the second quarter of 2016. For more information, and if you have ideas of how to make use of the capability on HRS in this limited time period, please contact us at salthelp@salt.ac.za.


SALT polarimetry update
=======================

The RSS polarimetry beamsplitter was returned to its US manufacturer in 2013 after problems were discovered with leaking coupling fluid. An alternative coupling "gel" was used in the repair and the beamsplitter was successfully re-installed into RSS in June 2015. The recommissioning of the mechanical and electrical mechanisms and control software associated with the polarimetry mode has been ongoing over the past few months. As of October 2015, closed dome re-commissioning tests are almost complete. On-sky commissioning and calibrations are scheduled to begin in October/November 2015.  We hope some of the polarimetry modes will be ready to be advertised for the SALT 2016-1 Semester Call, but at this point we are not certain yet. We will keep users informed. For more information about RSS polarimetry, please send any queries to salthelp@salt.ac.za.


RSS Guider
===========

A new RSS guider project is progressing well with proof-of-concept hardware for the motion stage and stand-alone control system on its way and concept designs of all the major components under way. This new two-probe design will be able to deliver rotation guidance (which especially MOS mode users will appreciate) and automatic focus feedback (which the observers will greatly appreciate), while delivering significantly improved performance with much fainter stars, reaching the same V~20 mag in 15 sec sensitivity as the current FIF guider. It is expected to be ready for integration with the telescope towards the end of 2016.


Tracker Upgrade
===============

Last week, the telescope was taken offline for the installation of the new Y-drive motors. The installation went smoothly and the telescope was back online and in operation after only two nights of down time.  The final stage of the upgrade is expected to be carried out in April 2016 and will result in a much better performing and capable tracker for the telescope.   Congratulations to the TechOps team for successfully carrying out this major milestone!

Phase II updates for 2015-2

** As a reminder, the Phase II deadline is 23 October 2015 **


Tips for Creating your Phase II proposal
========================================

Tips for creating your phase II proposal:

When creating your phase II proposal for next semester, there is no need for you to retype all the maximum lunar phases you chose in your phase I proposal. You can instead use version 4.7 of the PIPT to copy the phase values, as described at the bottom of

http://astronomers.salt.ac.za/proposals/tips-and-tricks/

This new version of the PIPT is now available, and can be downloaded from

http://astronomers.salt.ac.za/software/

You don't have to use this version for submitting your proposal. However, if you are planning to use pools in your proposal, you'll at least have to update to version 4.6 of the PIPT.

If you are a Mac user and have upgraded to El Capitan already, you might notice that the PIPT GUI is rather wonky. This seems to be an issue with Java 6, and upgrading to Java 8 should solve the problem.


Fabry-Perot Status
==================

As already communicated to FP users directly, the coatings of the Medium Resolution MR etalon have unfortunately degraded resulting in significant loss of spectral resolution.  We have removed it from the telescope and are in the process of determining both costs and timescales for repairs - but we do not expect it will be returned to the telescope for several months.

On the positive side, LR is working well, and the HR etalon has been inserted and we are working to commission the dual etalon HR mode in November.  If this effects your program, please contact salthelp@salt.ac.za for more information.


New P4 Policy
=============

There is a new policy on P4 Blocks allowing any accepted program to enter P4 targets to the queue, above their time allocation. These are to be used as filler targets in case we have nothing else available at a given time.  If you are unsure what it means, first read the bits about P4 time in the Intro and Section 11.4 of the http://pysalt.salt.ac.za/proposal_calls/current/ProposalCall.html and discuss with your Liaison Astronomer. Note that using optional targets in pools is more useful in general.


Block Probability
=================

Before the 2015-2 Semester starts, there will be a new 'Block Probability' number on the Web Manager attached to each active  Phase II block.  The intention is to indicate roughly the chances of a block getting done.  The number takes into account Moon phase and Seeing constraints, the 'Observability' i.e. how tight the requested track is within its visibility window, and Competition from all other Blocks in that same window taking into account their Priorities.  Note that in case of multiple visits the number refers to the binomial probability of finishing *all* the requested visits taking into account the available tracks over the semester.

The system is live, so you can see the effects when e.g. changing seeing and lunar phase constraints.  It also means that the numbers before at least the great majority of Phase II blocks are active do not mean much since the competition calculation will be unrealistic.

it may still contain bugs. Please let us know if you think your nubmers
are showing anomalous behaviour.

Southern African Large Telescope reveals too large a black hole

The Southern African Large Telescope (SALT), Africa’s most powerful eye on the sky, has been used to discover a supermassive black hole in the centre of a modest galaxy, SAGE0536AGN. All but the smallest galaxies are thought to harbour a black hole, but in this case the black hole was found to be thirty times more massive than what one would have expected for this size galaxy. It leaves scientists scratching their heads in pursuit of an explanation.

The presence of a black hole was suspected when the infrared emission from its dusty environs was discovered in 2009 using NASA’s Spitzer Space Telescope. Now, scientists from the United Kingdom SALT Consortium, Jacco van Loon from Keele University and Anne Sansom from the University of Central Lancashire used the SALT to take a spectrum of the galaxy. The spectrum showed emission at particular wavelengths related to hydrogen gas, but shifted to redder wavelengths than on Earth due to the large recession velocity of the galaxy, placing it at a distance from which light took 1.86 billion years to reach us. This already indicated that the central engine of the galaxy must be very luminous. The spread in wavelength of the hydrogen emission betrayed gas moving very rapidly in the strong gravitational field of the black hole, and from this the mass of the black hole was determined to be 350 million times that of the Sun. For comparison, this is a hundred times more massive than the black hole that lives in the centre of our own Milky Way. However, when they also measured the mass of the galaxy itself, from the absorption of light by heavier atoms, they were surprised to find the galaxy’s mass to be a mere 25 billion times that of the Sun, less than that of the Milky Way!

Says Jacco van Loon: “For a long time, scientists have been trying to explain the good observed relationship between the mass of the black hole and the mass of the galaxy host. Now they will need to start explaining how some systems can deviate so much from this relationship.”
Because the galaxy was only found by accident in the distant background of a survey meant to study a very nearby dwarf galaxy, surveys aimed at finding extragalactic supermassive black holes may have missed more systems like SAGE0536AGN. SALT may thus have opened a new window, and a new view of how galaxies and their central engines have grown over time.
