    The JWST-SUSPENSE Ultradeep Spectroscopic Program: Survey Overview and Star Formation Histories of Quiescent Galaxies at 1 < z < 3 by Martje Slob, Mariska Kriek, Aliza G. Beverage, Katherine A. Suess, Guillermo Barro, Rachel Bezanson, Gabriel Brammer, Chloe M. Cheng, Charlie Conroy, Anna de Graaff, Natascha M. Förster Schreiber, Marijn Franx, Brian Lorenz, Pavel E. Mancera Piña, Danilo Marchesini, Adam Muzzin, Andrew B. Newman, Sedona H. Price, Alice E. Shapley, Mauro Stefanon, Pieter van Dokkum, Daniel R. Weisz

    Published 2024-01-01
    “…Furthermore, the typical SFHs of the galaxies in these two redshift bins ( z _mean = 2.2 [1.3]) indicate that galaxies at higher redshift formed earlier and over shorter star formation timescales compared to lower redshifts. Although this evolution is naturally explained by the growth of the quiescent galaxy population over cosmic time, number density calculations imply that mergers and/or late-time star formation also contribute to the evolution. …”

    Unveiling the Cosmic Chemistry: Revisiting the Mass–Metallicity Relation with JWST/NIRSpec at 4 < z < 10 by Arnab Sarkar, Priyanka Chakraborty, Mark Vogelsberger, Michael McDonald, Paul Torrey, Alex M. Garcia, Gourav Khullar, Gary J. Ferland, William Forman, Scott Wolk, Benjamin Schneider, Mark Bautz, Eric Miller, Catherine Grant, John ZuHone

    Published 2025-01-01
    “…Beyond z = 8, we observe a significant deviation (∼0.27 dex) in FMR, consistent with recent JWST findings. We also integrate Cosmic Evolution Early Release Science (135 galaxies) and JADES (47 galaxies) samples with our data to study the metallicity evolution with redshift in a combined sample of 263 galaxies, revealing a decreasing metallicity trend with a slope of 0.067 ± 0.013, consistent with IllustrisTNG and EAGLE but contradicting the FIRE simulations. …”

    The PANORAMIC Survey: Pure Parallel Wide Area Legacy Imaging with JWST/NIRCam by Christina C. Williams, Pascal A. Oesch, Andrea Weibel, Gabriel Brammer, Aidan P. Cloonan, Katherine E. Whitaker, Laia Barrufet, Rachel Bezanson, Rebecca A. A. Bowler, Pratika Dayal, Marijn Franx, Jenny E. Greene, Anne Hutter, Zhiyuan Ji, Ivo Labbé, Sinclaire M. Manning, Michael V. Maseda, Mengyuan Xiao

    Published 2025-01-01
    “…Pure parallel observing naturally creates a “wedding cake” survey with both wide and ultra-deep tiers, with 5 σ point-source depths at F444W ranging from 27.8–29.4 (ABmag), and with minimized cosmic variance. …”

    The MBH–M∗ Relation up to z ∼ 2 through Decomposition of COSMOS-Web NIRCam Images by Takumi S. Tanaka, John D. Silverman, Xuheng Ding, Knud Jahnke, Benny Trakhtenbrot, Erini Lambrides, Masafusa Onoue, Irham Taufik Andika, Angela Bongiorno, Andreas L. Faisst, Steven Gillman, Christopher C.

    Published 2025-01-01
    “…Considering selection biases and measurement uncertainties, we find that the M _BH / M _* ratio evolves as ${\left(1+z\right)}^{0.4{8}_{-0.62}^{+0.31}}$ thus remains essentially constant or exhibits mild evolution up to z  ∼ 2.5. We also see an amount of scatter ( ${\sigma }_{\mu }=0.3{0}_{-0.13}^{+0.14}$ ), similar to the local relation and consistent with low- z studies, and a noncausal cosmic assembly history where mergers contribute to the statistical averaging toward the local relation is still feasible. …”

    Detectability of Self-lensing Flares of White Dwarfs with Compact Companions by Guy Nir, Joshua S. Bloom

    Published 2025-01-01
    “…We provide a quantitative analysis of the detectability of double-compact object self-lensing flares across the landscape of system parameters, and a qualitative discussion of survey and follow-up approaches to distinguish such flares from confounding events, such as stellar flares, satellite glints, and cosmic rays. …”

    On the Formation of Planets in the Milky Way’s Thick Disk by Tim Hallatt, Eve J. Lee

    Published 2025-01-01
    “…Exoplanet demographic surveys have revealed that close-in (≲1 au) small planets orbiting stars in the Milky Way’s thick disk are ∼50% less abundant than those orbiting stars in the Galactic thin disk. …”
