Type Ia supernovae

Stéphane Blondin

Type Ia supernovae (SNe Ia) correspond to the thermonuclear explosion of a carbon-oxygen white dwarf (C-O WD) star in a binary system, triggered by the accretion of material from a…

GRB 211024B: an ultra-long GRB powered by magnetar

Shao-Yu Fu, Dong Xu, Wei-Hua Lei +15

Ultra-long gamma-ray bursts (ULGRBs) are characterized by exceptionally long-duration central engine activities, with characteristic timescales exceeding 1000 seconds. We present g…

A simple model of dust extinction in gamma-ray burst host galaxies

N. A. Rakotondrainibe, V. Buat, D. Turpin +4

Gamma-ray burst (GRB) afterglows are powerful probes for studying the different properties of their host galaxies (e.g., the interstellar dust) at all redshifts. By fitting their s…

An Eddington Limited Accretion Disk Wind in the narrow line Seyfert 1, PG 1448+273

J. N. Reeves, V. Braito, A. Luminari +5

PG 1448+273 is a luminous, nearby (), narrow line Seyfert 1 galaxy, which likely accretes close to the Eddington limit. Previous X-ray observations of PG 1448 with XMM-Ne…

HI and CO spectroscopy of the unusual host of GRB 171205A: A grand design spiral galaxy with a distorted HI field

A. de Ugarte Postigo, M. Michalowski, C. C. Thoene +22

GRBs produced by the collapse of massive stars are usually found near the most prominent star-forming regions of star-forming galaxies. GRB 171205A happened in the outskirts of a s…
