Extreme outflow velocities and weak UV emission lines indicate quasars shedding their dust cocoons

Guozhen Ma, Stefan J. Geier, Johan P. U. Fynbo +11

The recently discovered low-ionisation broad absorption line (LoBAL) quasar GQ 13092904 is unusual due to its very broad, highly blueshifted absorption troughs and an absence of…

A Radio Flare in the Long-Lived Afterglow of the Distant Short GRB 210726A: Energy Injection or a Reverse Shock from Shell Collisions?

Genevieve Schroeder, Lauren Rhodes, Tanmoy Laskar +32

We present the discovery of the radio afterglow of the short -ray burst (GRB) 210726A, localized to a galaxy at a photometric redshift of . While radio observations c…

JWST detection of heavy neutron capture elements in a compact object merger

A. Levan, B. P. Gompertz, O. S. Salafia +80

The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…

CO Excitation and Line Energy Distributions in Gas-selected Galaxies

A. Klitsch, L. Christensen, F. Valentino +6

While emission-selected galaxy surveys are biased towards the most luminous part of the galaxy population, absorption selection is a potentially unbiased galaxy selection technique…

GRB host galaxies with strong H absorption: CO-dark molecular gas at the peak of cosmic star formation

K. E. Heintz, G. Björnsson, M. Neeleman +13

We present a pilot search of CO emission in three H-absorbing, long-duration gamma-ray burst (GRB) host galaxies at z~2-3. We used the Atacama Large Millimeter/sub-millimeter A…

A more probable explanation for a continuum flash in the direction of a redshift 11 galaxy

Charles L. Steinhardt, Michael I. Andersen, Gabriel B. Brammer +5

Recent work reported the discovery of a gamma-ray burst (GRB) associated with the galaxy GN-z11 at . The extreme improbability of the transient source being a GRB in the…
