Optical transients from non-explosive double white-dwarf mergers: the case of a central neutron star remnant

M. M. Ridha Fathima, Alexandre M. R. Almeida, Mattia Bulla +3

Discoveries of ultra-massive magnetic white dwarfs (WDs) and peculiar pulsars have been proposed to originate in double white dwarf (DWD) mergers. There are three possible post-mer…

Detection of disk-jet co-precession in a tidal disruption event

Yanan Wang, Zikun Lin, Linhui Wu +46

Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…

A set of distinctive properties ruling the prompt emission of GRB 230307A and other long γ-ray bursts from compact object mergers

R. Maccary, C. Guidorzi, M. Maistrello +9

Short gamma-ray bursts (SGRBs), occasionally followed by a long and spectrally soft extended emission, are associated with compact object mergers (COMs). Yet, a few recent long GRB…

Exploring GRBs and supernovae connection: does a superluminous hypernova population exist?

Achille Fiore, Ludovica Crosato Menegazzi, Giulia Stratta

Observations of several gamma-ray bursts (GRBs) that are temporally and spatially compatible with energetic supernovae (hypernovae) has established their common origin. In one case…

Distribution of number of peaks within a long gamma-ray burst

C. Guidorzi, M. Sartori, R. Maccary +10

The variety of long duration gamma-ray burst (LGRB) light curves (LCs) encode a wealth of information on how LGRB engines release energy following the collapse of the progenitor st…

Minutes-duration Optical Flares with Supernova Luminosities

Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74

In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…
