All the Little Things in Abell 2744: 1000 Gravitationally Lensed Dwarf Galaxies at from JWST NIRCam Grism Spectroscopy

Rohan P. Naidu, Jorryt Matthee, Ivan Kramarenko +31

Dwarf galaxies hold the key to crucial frontiers of astrophysics, however, their faintness renders spectroscopy challenging. Here we present the JWST Cycle 2 survey, All the Little…

Detecting and Characterizing Young Quasars II: Four Quasars at with Lifetimes years

Anna-Christina Eilers, Joseph F. Hennawi, Frederick B. Davies +1

The extents of proximity zones of high-redshift quasars enable constraints on the timescales of quasar activity, which are fundamental for understanding the growth of the supermass…

Interstellar and Circumgalactic Properties of an Unseen Galaxy: Abundances, Ionization, and Heating in the Earliest Known Quasar Absorber

Robert A. Simcoe, Masafusa Onoue, Anna-Christina Eilers +5

We analyze relative abundances and ionization conditions in a strong absorption system at z=6.84, seen in the spectrum of the z=7.54 background quasar ULAS J134208.10+092838.61. Si…
