A comparison of methods for Poisson regression in the presence of background
Massimiliano Bonamente, Vinay Kashyap, Xiaoli Li +1
This paper provides a statistical analysis of three common methods of regression for Poisson data in the presence of Poisson background, namely the joint fit with two parametric mo…
A simple, flexible method for timing cross-calibration of space missions
Matteo Bachetti, Yukikatsu Terada, Megumi Shidatsu +25
The timing (cross-)calibration of astronomical instruments is often done by comparing pulsar times-of-arrival (TOAs) to a reference timing model. In high-energy astronomy, the choi…
Detecting stellar flares in the presence of a deterministic trend and stochastic volatility
Qiyuan Wang, Giovanni Motta, Genaro Sucarrat +1
We develop a new and powerful method to analyze time series to rigorously detect flares in the presence of an irregularly oscillatory baseline, and apply it to stellar light curves…
XRISM view of a stellar flare: High-resolution Fe K spectra of HR 1099, an RS CVn-type star
Miki Kurihara, Masahiro Tsujimoto, Michael Loewenstein +21
A high-resolution X-ray spectroscopic observation was made of the RS CVn-type binary star HR 1099 using the Resolve instrument onboard XRISM for its calibration purposes. During th…
Representation Learning for Time-Domain High-Energy Astrophysics: Discovery of Extragalactic Fast X-ray Transient XRT 200515
Steven Dillmann, Juan Rafael MartÃnez-Galarza, Roberto Soria +2
We present a novel representation learning method for downstream tasks like anomaly detection, unsupervised classification, and similarity searches in high-energy data sets. This e…
