The highest-energy gamma-rays from gamma-ray bursts (GRBs) have important implications
for their radiation mechanism. Here we report the detection of gamma-rays up to 13 …

We present an updated model of the cosmic ionizing background from the UV to the X-rays.
Relative to our previous model, the new model provides a better match to a large number of …

We use the energy-balance code magphys to determine stellar and dust masses, and dust
corrected star formation rates for over 200 000 GAMA galaxies, 170 000 G10-COSMOS …

We report on the host association of FRB 20181030A, a repeating fast radio burst (FRB) with
a low dispersion measure (103.5 pc cm− 3) discovered by the CHIME/FRB Collaboration et …

The diffuse extragalactic background light (EBL) is formed by ultraviolet (UV), optical, and
infrared (IR) photons mainly produced by star formation processes over the history of the …

The cosmic infrared background (CIB) contains emissions accumulated over the entire
history of the Universe, including from objects inaccessible to individual telescopic studies …

The light emitted by all galaxies over the history of the Universe produces the extragalactic
background light (EBL) at ultraviolet, optical, and infrared wavelengths. The EBL is a source …

We present the host galaxies of four apparently nonrepeating fast radio bursts (FRBs), FRB
20181223C, FRB 20190418A, FRB 20191220A, and FRB 20190425A, reported in the first …

A radiative decaying big bang relic with a mass ma≃ 5–25 eV, which we dub “blue axion,”
can be probed with direct and indirect observations of the cosmic optical background (COB) …

We present new synthesis models of the extragalactic background light (EBL) from far infra-
red (FIR) to TeV γ-rays, with an emphasis on the extreme ultraviolet (UV) background that is …
