The high entropy of the UHECR arrival direction distribution favors a light composition
Nimrod Strasman, Eli Waxman
We analyze the constraints on the composition of ultra-high-energy cosmic rays (UHECRs), and on the density and distribution of their sources, that may be inferred from their arriv…

A search for minute-time-scale flares from the transient AT\,2024wpp
Eran O. Ofek, Lior Ozer, Ruslan Konno +21
The AT 2018cow-like fast blue optical transient AT2022tsd showed a large number of few-minute-duration, high-luminosity (~10^43 erg/s) flares. We present an intensive search for su…
