Classification of IGR J20084+3221 as an Intermediate Polar using X-ray and Optical Observations
Julian Gerber, Jeremy Hare, John A. Tomsick +2
IGR J20084+3221 is a previously unclassified Galactic source first detected by INTEGRAL. Chandra observations led to possible classifications of either a magnetic Cataclysmic Varia…
Spectral and photometric variability of SS 433 observed with XRISM and simultaneous optical and near-infrared telescopes
Yusuke Sakai, Shinya Yamada, Yuta Okada +36
We present results from coordinated multiwavelength observations of the SS 433, obtained with XRISM, optical telescopes, and near-infrared camera during 2024 April and 2025 March.…
Revealing the accelerating wind in the inner region of the colliding-wind binary WR 112
John D. Monnier, Yinuo Han, Michael F. Corcoran +17
Colliding winds in massive binaries generate X-ray-bright shocks, synchrotron radio emission, and sometimes even dusty "pinwheel" spirals. We report the first X-ray detections of t…
Solar Cycle Variation of Sustained Gamma Ray Emission from the Sun
Nat Gopalswamy, Pertti Mäkelä, Seiji Yashiro +3
We investigated the occurrence rate of the sustained gamma ray emission (SGRE) events from the Sun using data obtained by Fermi Large Area Telescope (LAT) since its launch in 2008.…
The Intermediate Mass Black Hole in Omega Centauri: Constraints on Accretion from JWST
Steven Chen, Jeremy Hare, Oleg Kargaltsev +4
We analyze JWST observations of the central region of the globular cluster Centauri (NGC 5139, Cen hereafter), around the position of the candidate IMBH inferred by \cite{h…
Testing Magnetic Field Configurations in Spider Pulsar PSR J1723-2837 with IXPE
Michela Negro, Haocheng Zhang, Niccolò Di Lalla +4
We present the first X-ray polarimetry observations of a redback millisecond pulsar binary, PSR J1723-2837, with the Imaging X-ray Polarimetry Explorer (IXPE). We conduct a spectro…
