Spectroscopic characterization of a remarkable temporally varying, triple-lensed quasar at z=2.67
Charlie Lind-Thomsen, Kasper E. Heintz, Albert Sneppen +5
Gravitationally lensed quasars are viable cosmic tools for constraining a diversity of fundamental astrophysical phenomena; They enable identification of faint, low-mass supermassi…
GRB 180728A and SN 2018fip: the nearest high-energy cosmological gamma-ray burst with an associated supernova
A. Rossi, L. Izzo, K. Maeda +29
The long GRB 180728A, at a redshift of , stands out due to its high isotropic energy of erg, in contrast with most events at redshi…
On the Dusty Proximate Damped Lyman-α System toward Q2310-3358 at z = 2.40
S. Han, J. -K. Krogager, C. Ledoux +6
Quasar absorption systems not only affect the way quasars are selected, but also serve as key probes of galaxies, providing insight into their chemical evolution and interstellar m…
GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels
Dimple, B. P. Gompertz, A. J. Levan +85
Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…
SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization
B. Cordier, J. Y. Wei, N. R. Tanvir +103
Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…
A large, chemically enriched, neutral gas reservoir in a galaxy at z = 6.782
A. Saccardi, S. D. Vergani, L. Izzo +23
The chemical characterization of galaxies in the first billion years after the Big Bang is one of the central goals of current astrophysics. Optical/near-infrared spectroscopy of l…
