An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: I. The properties of the 870 micron counterparts
E. Hatziminaoglou, H. Messias, R. Souza +6
(Abridged) Quasar studies with Herschel/SPIRE often report host luminosities ranging from 10^{12} to 10^{14} Lsun, suggestive of star formation rates (SFRs) of up to several thousa…
The ambiguous AT2022rze: Changing-look AGN mimicking a supernova in a merging galaxy system
P. J. Pessi, R. Lunnan, J. Sollerman +36
AT2022rze is a luminous, ambiguous transient located South-East of the geometric center of its host galaxy at redshift z = 0.08. The host appears to be formed by a merging galaxy s…
An extremely soft and weak fast X-ray transient associated with a luminous supernova
W. -X. Li, Z. -P. Zhu, X. -Z. Zou +101
Long gamma-ray bursts (LGRBs), including their subclasses of low-luminosity GRBs (LL-GRBs) and X-ray flashes (XRFs) characterized by low spectral peak energies, are known to be ass…
Unveiling dust, molecular gas, and high star formation efficiency in extremely UV bright star-forming galaxies at
M. Dessauges-Zavadsky, R. Marques-Chaves, D. Schaerer +4
We analysed ALMA FIR (1.3 mm) dust continuum and CO emission of 12 starburst galaxies at , selected for their extreme brightness in the rest-UV with $M_{\rm UV} = -2…
Eruptive mass loss less than a year before the explosion of superluminous supernovae: I. The cases of SN 2020xga and SN 2022xgc
A. Gkini, C. Fransson, R. Lunnan +47
We present photometric and spectroscopic observations of SN 2020xga and SN 2022xgc, two hydrogen-poor superluminous supernovae (SLSNe-I) at and , respectiv…
Evidence for Very Massive Stars in extremely UV-bright star-forming galaxies at
A. Upadhyaya, R. Marques-Chaves, D. Schaerer +4
We present a comprehensive analysis of the presence of very massive stars (VMS > ) in the integrated spectra of 13 UV-bright star-forming galaxies at $2.2 \lesssim z…
