Flux and polarization variability of OJ 287 during early 2016 outburst
Suvendu Rakshit, C. S. Stalin, S. Muneer +2
The gamma-ray blazar OJ 287 was in a high activity state during December 2015 - February 2016. Coinciding with this high brightness state, we observed this source for photometry on…
The NuSTAR Serendipitous Survey: The 40 month Catalog and the Properties of the Distant High Energy X-ray Source Population
G. B. Lansbury, D. Stern, J. Aird +35
We present the first full catalog and science results for the NuSTAR serendipitous survey. The catalog incorporates data taken during the first 40 months of NuSTAR operation, which…
Spontaneous atomicity for polynomial rings with zero-divisors
Jim Coykendall, Stacy Trentham
In this paper, we show that it is possible for a commutative ring with identity to be non-atomic (that is, there exist non-zero nonunits that cannot be factored into irreducibles)…
Intra-night optical variability characteristics of different classes of narrow line Seyfert 1 galaxies
Kshama S. K., Vaidehi S. Paliya, C. S. Stalin
In a first systematic effort to characterize the intra-night optical variability (INOV) of different classes of narrow line Seyfert 1 (NLSy1) galaxies, we have carried out observat…
Algebraic multigrid support vector machines
Ehsan Sadrfaridpour, Sandeep Jeereddy, Ken Kennedy +3
The support vector machine is a flexible optimization-based technique widely used for classification problems. In practice, its training part becomes computationally expensive on l…
Multi-epoch Spectropolarimetry of SN 2011fe
Peter A. Milne, G. Grant Williams, Amber Porter +5
We present multiple spectropolarimetric observations of the nearby Type Ia supernova (SN) 2011fe in M101, obtained before, during, and after the time of maximum apparent visual bri…
