Dust masses for SN 1980K, SN1993J and Cassiopeia A from red-blue emission line asymmetries
Antonia Bevan, M. J. Barlow, D. Milisavljevic
We present Monte Carlo line transfer models that investigate the effects of dust on the very late time emission line spectra of the core collapse supernovae SN 1980K and SN 1993J a…
An ultraviolet excess in the superluminous supernova Gaia16apd reveals a powerful central engine
M. Nicholl, E. Berger, R. Margutti +5
Since the discovery of superluminous supernovae (SLSNe) in the last decade, it has been known that these events exhibit bluer spectral energy distributions than other supernova sub…
X-rays from the location of the Bactrian Transient ASASSN-15lh
R. Margutti, B. D. Metzger, R. Chornock +13
We present the detection of persistent soft X-ray radiation with L_x ~ 10^41-10^42 erg/s at the location of the extremely luminous, double-humped transient ASASSN-15lh as revealed…
The Gamma-ray Blazar Quest: new optical spectra, state of art and future perspectives
F. Massaro, N. Álvarez Crespo, R. D'Abrusco +13
We recently developed a procedure to recognize gamma-ray blazar candidates within the positional uncertainty regions of the unidentified/unassociated gamma-ray sources (UGSs). Such…
Optical archival spectra of blazar candidates of uncertain type in the 3 Fermi Large Area Telescope Catalog
N. Álvarez Crespo, F. Massaro, R. D'Abrusco +10
Despite the fact that blazars constitute the rarest class among active galactic nuclei (AGNs) they are the largest known population of associated -ray sources. Many of the -r…
Optical spectroscopic observations of -ray blazar candidates VI. Further observations from TNG, WHT, OAN, SOAR and Magellan telescopes
N. Álvarez Crespo, F. Massaro, D. Milisavljevic +16
Blazars, one of the most extreme class of active galaxies, constitute so far the largest known population of -ray sources and their number is continuously growing in the Fermi c…
Superluminous supernova 2015bn in the nebular phase: evidence for the engine-powered explosion of a stripped massive star
M. Nicholl, E. Berger, R. Margutti +25
We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light…
PTF12os and iPTF13bvn. Two stripped-envelope supernovae from low-mass progenitors in NGC 5806
C. Fremling, J. Sollerman, F. Taddia +19
We investigate two stripped-envelope supernovae (SNe) discovered in the nearby galaxy NGC 5806 by the (i)PTF. These SNe, designated PTF12os/SN 2012P and iPTF13bvn, exploded at a si…
Dead or Alive? Long-term evolution of SN 2015bh (SNhunt275)
N. Elias-Rosa, A. Pastorello, S. Benetti +37
Supernova (SN) 2015bh (or SNhunt275) was discovered in NGC 2770 on 2015 February with an absolute magnitude of Mr ~ -13.4 mag, and was initially classified as a SN impostor. Here w…
Constraining the Age and Distance of the Galactic Supernova Remnant G156.2+5.7 by H-alpha Expansion Measurements
Satoru Katsuda, Masaomi Tanaka, Tomoki Morokuma +2
We present deep H-alpha images of portions of the X-ray bright but optically faint Galactic supernova remnant G156.2+5.7, revealing numerous and delicately thin nonradiative filame…
PS1-14bj: A Hydrogen-Poor Superluminous Supernova With a Long Rise and Slow Decay
R. Lunnan, R. Chornock, E. Berger +27
We present photometry and spectroscopy of PS1-14bj, a hydrogen-poor superluminous supernova (SLSN) at redshift discovered in the last months of the Pan-STARRS1 Medium De…
Comparative Analysis of SN 2012dn Optical Spectra: Days -14 to +114
J. T. Parrent, D. A. Howell, R. A. Fesen +19
SN 2012dn is a super-Chandrasekhar mass candidate in a purportedly normal spiral (SAcd) galaxy, and poses a challenge for theories of type Ia supernova diversity. Here we utilize t…
SN 2015bn: a detailed multi-wavelength view of a nearby superluminous supernova
M. Nicholl, E. Berger, S. J. Smartt +42
We present observations of SN 2015bn (= PS15ae = CSS141223-113342+004332 = MLS150211-113342+004333), a Type I superluminous supernova (SLSN) at redshift . As well as bein…
Ejection of the massive Hydrogen-rich envelope timed with the collapse of the stripped SN2014C
Raffaella Margutti, A. Kamble, D. Milisavljevic +19
We present multi-wavelength observations of SN2014C during the first 500 days. These observations represent the first solid detection of a young extragalactic stripped-envelope SN…
