We present multi-wavelength observations of SN 2014C during the first 500 days. These
observations represent the first solid detection of a young extragalactic stripped-envelope …

The dominant mechanism and time-scales over which stripped-envelope supernovae (SNe)
progenitor stars shed their hydrogen envelopes are uncertain. Observations of Type Ib and …

We present optical observations of supernova SN 2014C, which underwent an
unprecedented slow metamorphosis from H-poor type Ib to H-rich type IIn over the course of …

We present early-phase panchromatic photometric and spectroscopic coverage spanning
the far-ultraviolet to near-infrared regime of the nearest hydrogen-rich core-collapse …

We present the results from our 7 yr long broadband X-ray observing campaign of SN
2014C with Chandra and NuSTAR. These coordinated observations represent the first look …

Context. We present observations of SN 2019tsf (ZTF19ackjszs) and SN 2019oys
(ZTF19abucwzt). These two stripped envelope (SE) Type Ib supernovae (SNe) suddenly …

We present a multi-epoch quantitative spectroscopic analysis of the Type IIn supernova
(Type IIn SN) 1994W, an event interpreted by Chugai et al. as stemming from the interaction …

We present the results from a multiyear radio campaign of the superluminous supernova
(SLSN) SN 2017ens, which yielded the earliest radio detection of an SLSN to date at the …

We present an extensive set of photometric and spectroscopic data for SN 2009jf, a nearby
Type Ib supernova (SN), spanning from∼ 20 d before B-band maximum to 1 yr after …

Supernova (SN) 2005ip was a Type IIn event notable for its sustained strong interaction with
circumstellar material (CSM), coronal emission lines and infrared (IR) excess, interpreted as …
