Revealing the state transition of Cen X-3 at high spectral resolution with Chandra

Kavli Affiliate: Norbert Schulz | First 5 Authors: Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Lida Oskinova, Konstantin Postnov, Jose Joaquín Rodes-Roca | Summary: Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportunity textit{Chandra} observation made during […]

First Resolution of Microlensed Images of a Binary-Lens Event

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Zexuan Wu, Subo Dong, A. Mérand, Christopher S. Kochanek, Przemek Mróz | Summary: We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary perturbations, complicating the analysis, but the […]

BASS. XLIII: Optical, UV, and X-ray emission properties of unobscured Swift/BAT active galactic nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Kriti K. Gupta, Claudio Ricci, Matthew J. Temple, Alessia Tortosa, Michael J. Koss | Summary: We present one of the largest multiwavelength studies of simultaneous optical-to-X-ray spectral energy distributions (SEDs) of unobscured active galactic nuclei (AGN) in the local Universe. Using a representative sample of hard-X-ray-selected AGN […]

SAGAbg II: the Low-Mass Star-Forming Sequence Evolves Significantly Between 0.05<z<0.21

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Marla Geha, Yao-Yuan Mao, Mithi A. C. de los Reyes, Risa H. Wechsler | Summary: The redshift-dependent relation between galaxy stellar mass and star formation rate (the Star-Forming Sequence, or SFS) is a key observational yardstick for galaxy assembly. We use the SAGAbg-A sample […]

SPECTER: An Instrument Concept for CMB Spectral Distortion Measurements with Enhanced Sensitivity

Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Alina Sabyr, Carlos Sierra, J. Colin Hill, Jeffrey J. McMahon, | Summary: Deviations of the cosmic microwave background (CMB) energy spectrum from a perfect blackbody uniquely probe a wide range of physics, ranging from fundamental physics in the primordial Universe ($mu$-distortion) to late-time baryonic feedback processes […]
