The Treasury of Extremely Metal-Poor O Stars
O. Grace Telford, Christiana Erba, Kristen B. W. McQuinn +10
The Treasury of Extremely Metal-Poor O Stars (TEMPOS) is a Hubble Space Telescope survey of hot and massive O-type stars in nearby, low-metallicity galaxies (20% of the s…
GLOW II: A Census of Oxygen in Low-Mass Galaxies
Kristen B. W. McQuinn, O. Grace Telford, Andrey V. Kravtsov +12
Oxygen is forged by stars and redistributed through galaxies by feedback-driven outflows, leaving a record of star formation and the baryon cycle imprinted on its present-day abund…
Scylla: Observational Evidence for an Order of Magnitude in Dust Mass Opacity Evolution with ISM Density in the Large Magellanic Cloud
Christina W. Lindberg, Christopher J. R. Clark, Claire E. Murray +11
The emissivity of dust is known to vary greatly with radiative environment, density, grain chemistry, and geometry. Discrepancies between dust mass surface densities derived from f…
The Panchromatic Hubble Andromeda Southern Treasury (PHAST). II. The Spatially Resolved Recent Star Formation History in M31
Tobin M. Wainer, Benjamin F. Williams, Zhuo Chen +19
We use Hubble Space Telescope optical imaging from the Panchromatic Hubble Andromeda Southern Treasury (PHAST) to measure the spatially resolved recent star formation history (SFH)…
Other red dots: A possible GLIMPSE of normal AGB stars at Cosmic Noon through extreme lensing
Lukas J. Furtak, Adi Zitrin, Erik Zackrisson +18
We report the discovery of four extremely faint () red point sources in recent ultra-deep JWST/NIRCam images of the strong lensing galaxy cluster Abell…
Scylla VI: Parsec-Scale Dust Extinction Maps in the SMC and LMC
Christina W. Lindberg, Claire E. Murray, Christopher J. R. Clark +14
We present a novel methodology for mapping dust extinction in nearby galaxies at parsec-scale resolution. We apply it to HST 68 fields within the Small and Large Magellanic Clouds…
A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at
Tiger Yu-Yang Hsiao, John Chisholm, Danielle A. Berg +22
The competition between metal synthesis and feedback from massive stars establishes the mass-metallicity relation (MZR) at low-redshifts. Examining this relation at higher redshift…
Probing the IMF in the Early Universe -- Direct measurements in the Boötes I UFD with JWST/NIRCam
Keyi Ding, Mario Gennaro, Roberto J. Avila +20
The dependence of the stellar initial mass function (IMF) on star-formation environment, particularly at low metallicities and high redshifts, remains poorly constrained. Ultra-fai…
A GLIMPSE of the 99%: a census of the faintest galaxies during the epoch of reionization and its implications for galaxy formation models
Hakim Atek, Iryna Chemerynska, Lukas J. Furtak +19
We present a comprehensive study of the galaxy UV luminosity function (UVLF) at leveraging deep JWST observations from the GLIMPSE survey. Thanks to gravitational lensing,…
Extreme (Rogue) Waves: From Theory to Experiments in Ultracold Gases and Beyond
A. Chabchoub, P. Engels, P. G. Kevrekidis +4
In this Chapter, we review key theoretical and experimental advances in the study of extreme nonlinear wave events, called rogue waves (RWs), in both single-component attractively…
The Stellar Initial Mass Function down to 0.16M Towards the Small Magellanic Cloud
Roger E. Cohen, Mario Gennaro, Matteo Correnti +2
The presence (and nature) of variations in the stellar initial mass function (IMF) at substantially sub-solar masses and metallicities (0.5M, [M/H]1) r…
GLIMPSE-DDT spectroscopic properties of faint-end galaxies at : Towards first metal enrichment, dust production, and ionizing photon production
Yoshihisa Asada, Seiji Fujimoto, John Chisholm +16
Ultra-faint galaxies at high- are fundamental elements of the early galaxy assembly, and spectroscopic characterization of this population is essential to understand the earlies…
A GLIMPSE into the UV Continuum Slopes of the Faintest Galaxies in the Epoch of Reionization
Michelle C. Jecmen, John Chisholm, Hakim Atek +23
As observations have yet to constrain the ionizing properties of the faintest (M > -16) galaxies, their contribution to cosmic reionization remains unclear. The rest-fra…
GLIMPSE-D: Metallicity Decline in Faint Galaxies: Implications for [O III]+Hb Luminosity Function and Reionisation Budget
Damien Korber, Daniel Schaerer, Rui Marques-Chaves +13
We report the measurement of the R3=[O III]5008/Hb ratios for 54 galaxies in the GLIMPSE-D survey. Thanks to gravitational lensing, our sample includes galaxies with -20 < Muv < -1…
