Constraints on the narrow-line region of the X-ray quasi-periodic eruption source GSN 069
Kishore C. Patra, Wenbin Lu, Yilun Ma +4
The origins of quasi-periodic eruptions (QPEs) are poorly understood, although most theoretical explanations invoke an accretion disk around a supermassive black hole. The gas and…
Early-time Spectropolarimetry of the Aspherical Type II Supernova SN 2023ixf
Sergiy S. Vasylyev, Yi Yang, Alexei V. Filippenko +13
We present six epochs of optical spectropolarimetry of the Type II supernova (SN) 2023ixf ranging from 2 to 15 days after the explosion. Polarimetry was obtained with the Ka…
Early-Time Ultraviolet and Optical Hubble Space Telescope Spectroscopy of the Type II Supernova 2022wsp
Sergiy S. Vasylyev, Christian Vogl, Yi Yang +9
We report early-time ultraviolet (UV) and optical spectroscopy of the young, nearby Type II supernova (SN) 2022wsp obtained by the Hubble Space Telescope (HST)/STIS at about 10 and…
Spectropolarimetry of the type IIP supernova 2021yja: an unusually high continuum polarization during the photospheric phase
Sergiy S. Vasylyev, Yi Yang, Kishore C. Patra +9
We present six epochs of optical spectropolarimetry of the Type IIP supernova (SN) 2021yja ranging from 25 to 95 days after the explosion. An unusually high continuum linear…
The Core Normal Type Ia Supernova 2019np: An Overall Spherical Explosion with an Aspherical Surface Layer and an Aspherical 56Ni Core
Peter Hoeflich, Yi Yang, Dietrich Baade +10
Optical spectropolarimetry of the normal thermonuclear supernova SN2019np from -14.5 to +14.5 days relative to B-band maximum detected an intrinsic continuum polarization, p(cont),…
