Cold and Hot gas distribution around the Milky-Way-M31 system in the HESTIA simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Mitali Damle, Martin Sparre, Philipp Richter, Maan H. Hani, SebastiĆ”n E. Nuza | Summary: Recent observations have revealed remarkable insights into the gas reservoir in the circumgalactic medium (CGM) of galaxy haloes. In this paper, we characterise the gas in the vicinity of Milky Way and Andromeda […]

The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Lily L. Zhao, Debra A. Fischer, Eric B. Ford, Alex Wise, MichaĆ«l Cretignier | Summary: Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precision radial velocity (EPRV) exoplanet detection. Several methods […]

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, […]

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

Kavli Affiliate: Marshall Bautz | 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 […]

H$_2$-dominated Atmosphere as an Indicator of Second-generation Rocky White Dwarf Exoplanets

Kavli Affiliate: Sara Seager | First 5 Authors: Zifan Lin, Sara Seager, Sukrit Ranjan, Thea Kozakis, Lisa Kaltenegger | Summary: Following the discovery of the first exoplanet candidate transiting a white dwarf (WD), a "white dwarf opportunity" for characterizing the atmospheres of terrestrial exoplanets around WDs is emerging. Large planet-to-star size ratios and hence large […]

TESS Revisits WASP-12: Updated Orbital Decay Rate and Constraints on Atmospheric Variability

Kavli Affiliate: Avi Shporer | First 5 Authors: Ian Wong, Avi Shporer, Shreyas Vissapragada, Michael Greklek-McKeon, Heather A. Knutson | Summary: After observing WASP-12 in the second year of the primary mission, the Transiting Exoplanet Survey Satellite (TESS) revisited the system in late 2021 during its extended mission. In this paper, we incorporate the new […]
