SRGA J181414.6-225604: A new Galactic symbiotic X-ray binary outburst triggered by an intense mass loss episode of a heavily obscured Mira variable

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Kishalay De, Ilya Mereminskiy, Roberto Soria, Charlie Conroy, Erin Kara | Summary: We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using data from the Palomar Gattini-IR survey, we identify a spatially and temporally […]

Sampling with replacement vs Poisson sampling: a comparative study in optimal subsampling

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jiahui Zou, HaiYing Wang, , | Summary: Faced with massive data, subsampling is a commonly used technique to improve computational efficiency, and using nonuniform subsampling probabilities is an effective approach to improve estimation efficiency. For computational efficiency, subsampling is often implemented with replacement or through […]
