Completing the Arecibo Galaxy Environment Survey

AGES is an HI survey specifically designed to investigate various galactic environments with higher sensitivity than ALFALFA, and also with better spatial and velocity resolution than previous HI surveys. Science goals include: the HI mass function in different environments, the identification of gaseous tidal features and isolated neutral gas clouds, the spatial distribution and properties of HI-selected galaxies, and comparisons with numerical models of galaxy formation. We request 328.25h to complete AGES (with the exception of the Local Void field) in spring 2015. For the Local Void field, we request 120h in spring 2015, 83.75h in fall 2015 and 100h in future years. On the basis that the Local Void is likely to be actually scheduled for 50% of the nights for which the LST range is in night-time, we anticipate completion of this field in 2017. Outreach Abstract: The Arecibo Galaxy Environment Survey (normally known as AGES) is using the Arecibo Telescope to search for galaxies in a number of quite different areas of the local universe. These vary from the Virgo Cluster, where there are huge numbers of galaxies very close together, to the Local Void, a region where the few galaxies to be found are very spread out. How many other galaxies are in a region, and how close together they are, affects the way galaxies develop, but we are also finding other differences between the different areas that are left over from the time galaxies were first forming. By investigating these differences we are finding out more about how galaxies formed and how they are still developing today.

Remote Observing Request

Observer will travel to AO Remote Observing X In Absentia (instructions to operator)

Section I I - Time Request
The following times are in LST. For these observations night-time is required.

Begin ­ End Interval­Interval 0700 ­ 0930 0930 ­ 1145 1015 ­ 1300 1715 ­ 1815* 2

Days Needed at This Interval 5 62 31 96


Time Constraints (Must Be Justified in the Prop osal Text) * Can run until LST 2000 The Turn On Galfa Survey (TOGS) operates commensally with AGES and 15 minutes for startup and calibration is scheduled at the start or end of AGES session. The TOGS calibration takes a little under 10 minutes, and the operator takes around 5 minutes to start TOGS (which is done prior to starting the AGES command script). While the calibration can be done at any point during the session, TOGS obviously has to be started at the start; we thus request that when possible the TOGS calibration and startup time is scheduled at the start of the AGES session. TOGS calibration adds 47.25h to the time request for this semester. The Local Void field is requested for LST 1715 - 1815 to fit around other pro jects. Should time be available, it can be scheduled until LST 2000.
