Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs

P. Weber, T. P. Roberts, S. Hämmerich +28

Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…

Vacuum birefringence and the polarized X-ray emission from a radio magnetar

Rachael E. Stewart, Hoa Dinh Thi, George Younes +13

The paper presents phase- and energy-resolved X‑ray polarization measurements of the radio magnetar 1E 1547.0‑5408, finding high polarization degrees that support vacuum birefringe…

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…

The NANOGrav 15 yr Data Set: Customized Chromatic Noise Models

Bjorn Larsen, Jeremy G. Baier, Daniel J. Oliver +53

Pulsar timing arrays conduct low-frequency gravitational wave searches, which require comprehensive accounting of various noise sources to achieve robust results. Interstellar prop…

Discriminating blazar emission models with high-energy polarimetry: Multi-band predictions and detectability

Sara Capecchiacci, Ioannis Liodakis, Haocheng Zhang +2

Polarimetric properties of blazars provide key constraints on the acceleration mechanisms powering their relativistic jets, the high-energy emission processes involved, and the com…

Gravitational Wave Measurement of the - Intrinsic Scatter at High Redshift

Cayenne Matt, Kayhan Gültekin, Gabriella Agazie +109

The observed GWB spectrum is higher in amplitude than model predictions by a factor of 2-3. Using a semi-analytic model, we evaluate the effect of a high-scatter supermassive black…
