We present two hydrogen-rich superluminous supernovae (SLSNe): SN2103hx and PS15br. These objects, together with SN2008es, are the only SLSNe showing a distinct, broad H α feature during the photospheric phase; also, they show no sign of strong interaction between fast moving ejecta and circumstella...

We present an extensive analysis of the optical and ultraviolet (UV) properties of AT 2023clx, the closest optical/UV tidal disruption event (TDE) to date ( z = 0.01107), which occurred in the nucleus of the interacting low-ionization nuclear emission-line region (LINER) galaxy, NGC 3799. After corr...

ABSTRACT Type Iax supernovae (SNe Iax) are one of the most common subclasses of thermonuclear supernova and yet their sample size, particularly those observed shortly after explosion, remains relatively small. In this paper, we present photometric and spectroscopic observations of two SNe Iax discov...

Aims. We investigate the photometric characteristics of a sample of intermediate-luminosity red transients (ILRTs), a class of elusive objects with peak luminosity between that of classical novae and standard supernovae. Our goal is to provide a stepping stone in the path to reveal the physical orig...

Aims . Tidal disruptions of stars by supermassive black holes produce emission at different wavelengths, but the optical emission is of ambiguous origin. A unification scenario of tidal disruption events (TDEs) has been proposed to explain the different classes of X-ray and optically selected events...

ABSTRACT We present an analysis of 20 tidal disruption events (TDEs) host galaxies observed with the Multi-Unit Spectroscopic Explorer (MUSE) integral-field spectrograph on European Southern Observatory (ESO) Very Large Telescope (VLT). We investigate the presence of extended emission line regions (...

This is the reproduction package for the MNRAS Article "Accretion disc cooling and narrow absorption lines in the tidal disruption event AT 2019dsg" by Cannizzaro et al (2021). It contains the reduced optical data, the scripts used for the emission lines fitting and the code used to perform the host...
