Published in 2018 at "Publications of the Astronomical Society of Australia"

DOI: 10.1017/pasa.2018.35

Abstract: Abstract Type Ic supernovae can be classified as normal supernovae Ic, type Ic super-luminous supernovae, X-ray flash-connected supernovae, broad-line supernovae Ic, and gamma-ray burst-connected supernovae. Here we suggest an inner connection for all kinds of… read more here.

Published in 2021 at "Classical and Quantum Gravity"

DOI: 10.1088/1361-6382/ac0f39

Abstract: The heliocentric redshifts (z hel) reported for 150 type Ia supernovae in the Pantheon compilation are significantly discrepant from their corresponding values in the JLA compilation. Both catalogues include corrections to the redshifts and magnitudes… read more here.

Published in 2024 at "Publications of the Astronomical Society of the Pacific"

DOI: 10.1088/1538-3873/adbf4b

Abstract: Supernovae (SNe) come in various flavors and are classified into different types based on emission and absorption lines in their spectra. SN candidates are now abundant with the advent of large systematic sky surveys like… read more here.

Published in 2024 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stae1603

Abstract: Understanding the explosion mechanism and hydrodynamic evolution of core-collapse supernovae is a long-standing quest in astronomy. The asymmetries caused by the explosion are encoded into the line profiles which appear in the nebular phase of… read more here.

Published in 2024 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stae1977

Abstract: The most recent SH0ES measurement of the Hubble constant employs corrections of type Ia supernova magnitudes due to extinction in their host galaxies. These corrections are estimated using a probabilistic model which is trained on… read more here.

Published in 2017 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stw3350

Abstract: SN 2014J in M 82 is the closest Type Ia supernova (SN Ia) in decades. The proximity allows for detailed studies of supernova physics and provides insights into the circumstellar and interstellar environment. In this… read more here.

Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty093

Abstract: The massive star origins for Type IIP supernovae (SNe) have been established through direct detection of their red supergiants progenitors in pre-explosion observations; however, there has been limited success in the detection of the progenitors… read more here.

Published in 2019 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stz073

Abstract: In this catalog we compile information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) as well as all other bright (mpeak 6 17), spectroscopically confirmed supernovae found in 2017, totaling 308… read more here.

Published in 2019 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stz3203

Abstract: Supernovae (SNe) could be powerful probes of the properties of stars and galaxies at high redshifts in future surveys. Wide fields and longer exposure times are required to offset diminishing star formation rates and lower… read more here.

Published in 2017 at "Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences"

DOI: 10.1098/rsta.2016.0273

Abstract: Spectropolarimetry is one of the most powerful methods to study the multi-dimensional geometry of supernovae (SNe). We present a brief summary of the spectropolarimetric observations of stripped-envelope core-collapse SNe. Observations indicate that stripped-envelope SNe generally… read more here.

Published in 2019 at "Physical Review D"

DOI: 10.1103/physrevd.100.035008

Abstract: Dark matter (DM) which sufficiently heats a local region in a white dwarf will trigger runaway fusion, igniting a type Ia supernova (SN). In a companion paper, this instability was used to constrain DM heavier… read more here.
