EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?
P. G. Jonker, A. J. Levan, Xing Liu +41
Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…
A study in scarlet -- II. Spectroscopic properties of a sample of Intermediate Luminosity Red Transients
G. Valerin, A. Pastorello, E. Mason +65
We investigate the spectroscopic characteristics of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classical novae…
The Carnegie Supernova Project-I. Spectroscopic analysis of stripped-envelope supernovae
S. Holmbo, M. D. Stritzinger, E. Karamehmetoglu +14
An analysis leveraging 170 optical spectra of 35 stripped-envelope (SE) core-collapse supernovae observed by the Carnegie Supernova Project-I and published in a companion paper is…
The Carnegie Supernova Project-I. Optical spectroscopy of stripped-envelope supernovae
M. D. Stritzinger, S. Holmbo, N. Morrell +14
We present 170 optical spectra of 35 low-redshift stripped-envelope core-collapse supernovae observed by the Carnegie Supernova Project-I between 2004 and 2009. The data extend fro…
The supermassive black hole coincident with the luminous transient ASASSN-15lh
T. Krühler, M. Fraser, G. Leloudas +11
The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical nat…
The Carnegie Supernova Project I: methods to estimate host-galaxy reddening of stripped-envelope supernovae
M. D. Stritzinger, F. Taddia, C. R. Burns +11
We aim to improve upon contemporary methods to estimate host-galaxy reddening of stripped-envelope (SE) supernovae (SNe). To this end the Carnegie Supernova Project (CSP-I) SE SNe…
Metallicity at the explosion sites of interacting transients
F. Taddia, J. Sollerman, C. Fremling +8
Context. Some circumstellar-interacting (CSI) supernovae (SNe) are produced by the explosions of massive stars that have lost mass shortly before the SN explosion. There is evidenc…
Early-time light curves of Type Ib/c supernovae from the SDSS-II Supernova Survey
F. Taddia, J. Sollerman, G. Leloudas +6
We analyse the early-time optical light curves (LCs) of 20 Type Ib/c supernovae (SNe Ib/c) from the Sloan Digital Sky Survey (SDSS) SN survey II, aiming to study their properties a…
SN 2009N: Linking normal and subluminous type II-P SNe
K. Takáts, M. L. Pumo, N. Elias-Rosa +31
We present ultraviolet, optical, near-infrared photometry and spectroscopy of SN 2009N in NGC 4487. This object is a type II-P supernova with spectra resembling those of subluminou…
A metallicity study of 1987A-like supernova host galaxies
F. Taddia, J. Sollerman, A. Razza +6
The origin of the blue supergiant (BSG) progenitor of Supernova (SN) 1987A has long been debated, along with the role that its sub-solar metallicity played. We now have a sample of…
Supernova spectra below strong circum-stellar interaction
G. Leloudas, E. Y. Hsiao, J. Johansson +9
We construct spectra of supernovae interacting strongly with a circumstellar medium (CSM) by adding SN templates, a black-body continuum and an emission-line spectrum. In a Monte C…
Supernova 2008J: early time observations of a heavily reddened SN 2002ic-like transient
F. Taddia, M. D. Stritzinger, M. M. Phillips +19
We provide additional observational evidence that some Type Ia supernovae (SNe Ia) show signatures of circumstellar interaction (CSI) with hydrogen-rich material. Early phase optic…
An asymmetric explosion as the origin of spectral evolution diversity in type Ia supernovae
K. Maeda, S. Benetti, M. Stritzinger +10
Type Ia Supernovae (SNe Ia) form an observationally uniform class of stellar explosions, in that more luminous objects have smaller decline-rates. This one-parameter behavior allow…
