A hybrid type Ia supernova with an early flash triggered by helium-shell detonation
Ji-an Jiang, Mamoru Doi, Keiichi Maeda +22
Type Ia supernovae (SNe Ia) arise from the thermonuclear explosion of carbon-oxygen white dwarfs. Though the uniformity of their light curves makes them powerful cosmological dista…
Ultrafast outflows disappear in high radiation fields
Ciro Pinto, William Alston, Michael L. Parker +8
Ultrafast outflows (UFOs) are the most extreme winds launched by active galactic nuclei (AGN) due to their mildly-relativistic speeds (~0.1-0.3c) and are thought to significantly c…
Revealing the ultra-fast outflow in IRAS 13224-3809 through spectral variability
Michael L. Parker, William N. Alston, Douglas J. K. Buisson +6
We present an analysis of the long-term X-ray variability of the extreme narrow-line Seyfert 1 (NLS1) galaxy IRAS 13224-3809 using principal component analysis (PCA) and fractional…
