The identification of red, apparently massive galaxies at z> 7 in early James Webb Space
Telescope (JWST) photometry suggests a strongly accelerated time line compared to …

Spectral energy distribution (SED) fitting has been extensively used to determine the nature
of the faint radio source population. Recent efforts have combined fits from multiple SED …

FRB 20220610A is a high-redshift fast radio burst (FRB) that has not been observed to
repeat. Here, we present rest-frame UV and optical Hubble Space Telescope observations …

We present an analysis of the ultraviolet (UV) continuum slopes (β) for a sample of 172
galaxy candidates at 8< z phot< 16 selected from a combination of JWST NIRCam imaging …

There is compelling evidence that the most massive galaxies in the Universe stopped
forming stars due to the time-integrated feedback from their central super-massive black …

We present an analysis of the UV continuum slopes for a sample of $176 $ galaxy
candidates at $8< z_ {\mathrm {phot}}< 16$. Focusing primarily on a new sample of $125 …

JWST is discovering increasing numbers of quiescent galaxies 1--2 billion years after the
Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation and …

We present an efficient Bayesian method for estimating individual photometric redshifts and
galaxy properties under a pre-trained population model (pop-cosmos) that was calibrated …

The recent discovery of a galaxy at z= 7.3 with undetected optical emission lines and a blue
UV to optical continuum ratio in JWST spectroscopy is surprising and needs to be explained …

We show, using molecular data, that the enigmatic genus Urocorthylus Petrov, Mandelshtam
& Beaver from Southeast Asia belongs in the scolytine tribe, Dryocoetini, and not in the …
