The Immediate, Exemplary, and Fleeting echelle spectroscopy of SN 2023ixf: Monitoring acceleration of slow progenitor circumstellar material, driven by shock interaction
Danielle Dickinson, Dan Milisavljevic, Braden Garretson +12
We present high resolution WIYN/NEID echelle spectroscopy (R ,000) of the supernova (SN) 2023ixf in M101, obtained 1.51 to 18.51 days after explosion over nine epochs. D…

X-ray emission from helium star+black hole binaries as probes of tidally induced spin-up of second-born black holes
Koushik Sen, Aleksandra Olejak, Sambaran Banerjee
Tidally induced spin-up of stripped helium stars in short-period (<\,1\,d) binaries with black holes has been presented as one of the possible mechanisms to reproduce the high-spin…
