<p>Abstract: Kostov et al. (2021) report the discovery of the first transiting circumbinary planet, detected from a single sector of TESS data. ARCES observations played a role in helping to establish the parameters of the system. We briefly present an overview of this interesting planetary system and then discuss the challenges encountered in analyzing ARCES data to derive accurate radial velocities for this project.</p>

<p>We are developing a generalized Python-based reduction toolkit for optical spectroscopy, guided by traditional IRAF procedures, and specifically designed to do quick-look reductions for KOSMOS at APO. The package will also include test spectra for teaching basic reduction, and a standard set of reference calibration images for the instrument. Our hope is that PyKOSMOS will be suitable for many science-grade applications, and invite the APO community to participate in testing and improving it.</p>

<p>While many ARCES users are veteran observers who know what to expect when taking their data, newer users lack the intuition and experience to efficiently assess their raw data on the fly. Hence, I present a proof-of-concept version of the Echelle Visualization Tool (EVT). The EVT takes input parameters (variable and preset instrument characteristics) and outputs an interactive plot of the echelle orders as they would appear on the CCD. The EVT can also take an input line list to display the locations of spectral lines of interest on the CCD. Furthermore, the code for the EVT is written to minimize any adjustments that would need to be made in the event that ARCES is replaced by another echelle spectrograph. The intention of this project is not only to provide a planning tool that shows users what to expect during their observing run, but to facilitate precise yet uncomplicated count checks as data are taken throughout the night. The current version is not yet an accurate representation of ARCES. Rather, the purpose of this poster is to update the community and to gather feedback and requested features that will inform the development of the EVT moving forward.

<p>The APO Data Analysis Working Group surveyed the 3.5m Users in 2019 and found that most users still rely on IRAF/PyRAF for the reduction of their data from the 3.5m and 0.5m telescopes. The discontinued support of IRAF in the future, and the general trend toward a "Python-only" computing infrastructure in astronomy, puts the sustainability of the community's tried and trusted reduction pipelines with IRAF into jeopardy.</p>
<p>Introducing SpecLab! This is a Python-only data reduction facility that I have been developing over the past several years incrementally in spare time (on weekends and in the evenings). I started it because of the need to provide students a backup option for the imexam + DS9 convenience that is possible with IRAF.</p>
<p>Speclab has interactive GUI functionalities that are not available in any of the Python software packages yet developed by STScI and Astropy. SpecLab thus has pedagogical functionality with the intention of being used in undergrad and graduate classes to teach data reduction. It can also be used to provide publication-ready reductions via automated scripts.</p>
<p>In this poster, I present a demonstration of SpecLab’s imexam for quick look assessment of your raw data from any of the instruments on the 3.5m at APO. I also show a preview of identify and standard.</p>

<p>We present an ongoing research effort to identify ionization sources in nearby AGN using Apache Point Observatory (APO) and the Hubble Space Telescope (HST). We measure emission line ratios along the spatial extents of the narrow line region (NLR) using spectra from APO's Dual Imaging Spectrograph (DIS) and HST's Space Telescope Imaging Spectrograph (STIS). The spectra reveal prominent emission lines of ionized gas that can be primarily attributed to star formation or AGN ionization. We construct BPT diagrams and compare with HST color images to isolate these regions and determine their connection to the kinematics of the outflowing gasses. When combined with our ongoing study of mass outflow rates, these efforts will help further our overall goal of determining the effectiveness of AGN feedback on their host galaxies.</p>

<p>ARCTIC has been a workhorse in the field of exoplanet followup photometry, contributing to several recent discoveries. The instrument’s remarkable diffuser element, which broadens the source PSF into a wide, tophat-like profile, has pushed ground-based photometry to sub-millimagnitude precision. We summarize the instrument’s noise performance, show a fitted transit light curve, and offer our best observing practices for future observations.</p>
