Deciphering the unusual stellar progenitor of GRB 210704A
R. L. Becerra, E. Troja, A. M. Watson +16
GRB~210704A is a burst of intermediate duration (~s) followed by a fading afterglow and an optical excess that peaked about 7 days after the explosion. Its propert…
SN 2020uem: A Possible Thermonuclear Explosion within A Dense Circumstellar Medium (II) The Properties of The CSM from Polarimetry and Light Curve Modeling
Kohki Uno, Takashi Nagao, Keiichi Maeda +11
Type IIn/Ia-CSM supernovae (SNe IIn/Ia-CSM) are classified by their characteristic spectra, which exhibit narrow hydrogen emission lines originating from a strong interaction with…
SN 2020uem: A Possible Thermonuclear Explosion within A Dense Circumstellar Medium (I) The Nature of Type IIn/Ia-CSM SNe from Photometry and Spectroscopy
Kohki Uno, Keiichi Maeda, Takashi Nagao +18
We have performed intensive follow-up observations of a Type IIn/Ia-CSM SN (SN IIn/Ia-CSM), 2020uem, with photometry, spectroscopy, and polarimetry. In this paper, we report on the…
Detection of stellar light from quasar host galaxies at redshifts above 6
Xuheng Ding, Masafusa Onoue, John D. Silverman +41
The detection of starlight from the host galaxies of quasars during the reionization epoch () has been elusive, even with deep HST observations. The current highest redshift q…
Statistical properties of the nebular spectra of 103 stripped envelope core collapse supernovae
Qiliang Fang, Keiichi Maeda, Hanindyo Kuncarayakti +6
We present an analysis of the nebular spectra of 103 stripped envelope (SE) supernovae (SNe) collected from the literature and observed with the Subaru Telescope from 2002 to 2012,…
Intermediate Luminosity Type Iax SN 2019muj With Narrow Absorption Lines: Long-Lasting Radiation Associated With a Possible Bound Remnant Predicted by the Weak Deflagration Model
Miho Kawabata, Keiichi Maeda, Masayuki Yamanaka +23
We present comprehensive spectroscopic and photometric analyses of the intermediate luminosity Type Iax supernova (SN Iax) 2019muj based on multi-band datasets observed through the…
