The 30-Year Search for the Compact Object in SN 1987A
Dennis Alp, Josefin Larsson, Claes Fransson +32
Despite more than 30 years of searches, the compact object in Supernova (SN) 1987A has not yet been detected. We present new limits on the compact object in SN 1987A using millimet…
Testing the magnetar scenario for superluminous supernovae with circular polarimetry
Aleksandar Cikota, Giorgos Leloudas, Mattia Bulla +15
Superluminous supernovae (SLSNe) are at least 5 times more luminous than common supernovae (SNe). Especially hydrogen-poor SLSN-I are difficult to explain with conventional p…
Spectropolarimetry of Galactic stars with anomalous extinction sightlines
Aleksandar Cikota, Thiem Hoang, Stefan Taubenberger +8
Highly reddened type Ia Supernovae (SNe Ia) with low total-to-selective visual extinction ratio values, , also show peculiar linear polarization wavelength dependencies with p…
Mapping Circumstellar Matter with Polarized Light - The Case of Supernova 2014J in M82
Yi Yang, Lifan Wang, Dietrich Baade +11
Optical polarimetry is an effective way of probing the environment of supernova for dust. We acquired linear HST ACS/WFC polarimetry in bands , , and of the s…
