A massive AGB donor in Scutum X-1: Identification of the first Mira variable in an X-ray binary

Kavli Affiliate: Robert Simcoe | First 5 Authors: Kishalay De, Deepto Chakrabarty, Roberto Soria, Michael C. B. Ashley, Charlie Conroy | Summary: The symbiotic X-ray binary Sct X-1 was suggested as the first known neutron star accreting from a red supergiant companion. Although known for nearly 50 years, detailed characterization of the donor remains lacking, […]

Mid-infrared Variability of Low-redshift Active Galactic Nuclei : Constraints on a Hot Dust Component with a Variable Covering Factor

Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, , | Summary: We utilize mid-infrared multi-epoch data from Wide-field Infrared Survey Explorer (WISE) over a $sim10$-year period in W1 (3.4$mu$m) and W2 (4.6$mu$m) bands to investigate the structure of dusty torus in low-redshift ($0.15<zle 0.4$) active galactic nuclei […]

Constraining galaxy overdensities around three z~6.5 quasars with ALMA and MUSE

Kavli Affiliate: Ran Wang | First 5 Authors: Romain A. Meyer, Roberto Decarli, Fabian Walter, Qiong Li, Ran Wang | Summary: We quantify galaxy overdensities around three high-redshift quasars with known [CII] 158um companions: PJ231-20 (z=6.59), PJ308-21 (z=6.24) and J0305-3150 (z=6.61). Recent SCUBA2 imaging revealed the presence of 17 submillimeter galaxies (SMG) with sky separations […]

Magnetic Spirals in Accretion Flows Originated from Misaligned Magnetic Field

Kavli Affiliate: Feng Yuan | First 5 Authors: Weixiao Wang, Miikka S. Väisälä, Hsien Shang, Ruben Krasnopolsky, Zhi-Yun Li | Summary: Misalignment between rotation and magnetic field has been suggested to be one type of physical mechanisms which can easen the effects of magnetic braking during collapse of cloud cores leading to formation of protostellar […]

Development and characterization of a fast and low noise readout for the next generation X-ray CCDs

Kavli Affiliate: Sven Herrmann | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Peter Orel, R. Glenn Morris, Gregory Prigozhin | Summary: The broad energy response, low electronic read noise, and good energy resolution have made X-ray Charge-Coupled Devices (CCDs) an obvious choice for developing soft X-ray astronomical instruments over the last half century. They also […]

Co-evolution of the Brightest Cluster Galaxies and their Host Clusters in Illustris-TNG

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Mark Vogelsberger, Ivana Danjanov, | Summary: We use the Illustris-TNG simulations to explore the dynamic scaling relation between massive clusters and their central galaxies (BCGs). The Illustris TNG300-1 simulation we use includes 280 massive clusters with $M_{200} > 10^{14}$ M$_{odot}$ enabling a […]
