Cosmic Origins at AAS246 Anchorage, AK

Session: AGN SIG: Mobilizing the Next Decadal Survey
Date: Tuesday, June 10, 2025 | 10:00 AM AK – 11:30 AM AK
Building/Room: Egan Convention Center, Room 11/12

“AGN SIG: Mobilizing Toward the Next Decadal Survey.” Our overall agenda is to review recent progress on understanding black holes and galaxy evolution in the context of the Astro2020 goals, learn about NASA’s observational facilities on the horizon, and plan for the next decadal survey guiding the AGN community’s scientific priorities. Details of the session will soon follow, but please consider adding this to your itinerary if you’ll be at the AAS meeting or joining us remotely.

Session: Evolution of Galaxies I
Title: JUMPS: The JWST Ultimate Medium-band Photometry Survey
Speaker: Swara Ravindranath, JUMPS Team
NASA-Goddard Space Flight Center, Greenbelt, MD

Date: Tuesday, June 10, 2025 | 10:00 AM AK – 11:30 AM AK
Building/Room: Dena'ina Civic & Convention Center, Ballroom C

JWST medium band color selection has proved to be an efficient method for selecting strong emission line galaxies in the Epoch of Reionization. The JUMPS survey is employing this technique by observing 3 massive galaxy clusters (Abell 370, MACS0416 and MACS1149) using 4 long wavelength medium bands (F360M, F430M, F460M, and F480M) and using them in combination with existing observations in F410M band to select galaxies at 5.2 < z < 9.4. In addition, the JUMPS program is also obtaining parallel imaging at long wavelengths (F277W, F356, and F444W) with NIRISS in the same fields where short wavelength (F115W, F150W, and F200W) observations exist and the deep exposures can identify z > 13 galaxies using continuum breaks. In this talk, I will present the results on the UV luminosity function (UVLF) and estimate of the ionizing photon budget from the star forming galaxies in the reionization epoch based on the medium band selection that allows us to extend the UVLF to ultra-faint galaxies at 5.2 < z < 9.4 and the Lyman break selection for z > 13 galaxies.
