First IFU observations of two GRB host galaxies at cosmic noon with JWST/NIRSpec

B. Topçu, P. Schady, S. Wuyts +16

Long gamma-ray bursts (GRBs) serve as powerful probes of distant galaxies. Their luminous afterglow pinpoints galaxies independent of luminosity, in contrast to most flux-limited s…

Deciphering spatially resolved Lyman-alpha profiles in reionization analogs: the Sunburst Arc at cosmic noon

Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen +7

The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons,…

MALS discovery of a rare HI 21-cm absorber at : origin of the absorbing gas in powerful AGN

P. P. Deka, N. Gupta, H. W. Chen +14

We report a new, rare detection of HI 21-cm absorption associated with a quasar (only six known at ) here towards J2339-5523 at = 1.3531, discovered through the Mee…

Comparing emission- and absorption-based gas-phase metallicities in GRB host galaxies at using JWST

P. Schady, R. M. Yates, L. Christensen +34

Much of what is known of the chemical composition of the universe is based on emission line spectra from star forming galaxies. Emission-based inferences are, nevertheless, model-d…

Improving blazar redshift constraints with the edge of the Ly forest: 1ES 1553+113 and implications for observations of the WHIM

J. Dorigo Jones, S. D. Johnson, Sowgat Muzahid +6

Blazars are some of the brightest UV and X-ray sources in the sky and are valuable probes of the elusive warm-hot intergalactic medium (WHIM; K). However, man…

MALS SALT-NOT survey of MIR-selected powerful radio-bright AGN at 0<z<3.5

N. Gupta, G. Shukla, R. Srianand +20

We present results of an optical spectroscopic survey using SALT and NOT to build a WISE mid-infrared color-based, dust-unbiased sample of powerful radio-bright (200 mJy at 1.4…
