Consistent and non-consistent deformations of gravitational theories

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Marc Basquens, Bogar Díaz, Eduardo J. S. Villaseñor, | Summary: We study the internally abelianized version of a range of gravitational theories, written in connection tetrad form, and study the possible interaction terms that can be added to them in a consistent […]

On the robustness of the velocity anisotropy parameter in probing the stellar kinematics in Milky Way like galaxies: Take away from TNG50 simulation

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Lars Hernquist, Mark Vogelsberger, Xuejian Shen, Joshua S. Speagle | Summary: We analyze the velocity anisotropy of stars in real and energy space for a sample of Milky Way-like galaxies in the TNG50 simulation. We employ different selection criteria, including spatial, kinematic and metallicity cuts, […]

97 Eclipsing Quadruple Star Candidates Discovered in TESS Full Frame Images

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Saul A. Rappaport, Tamas Borkovits, Robert Gagliano | Summary: We present a catalog of 97 uniformly-vetted candidates for quadruple star systems. The candidates were identified in TESS Full Frame Image data from Sectors 1 through 42 through a combination of machine […]

The origin of the unfocused XMM-Newton background, its variability and lessons learned for ATHENA

Kavli Affiliate: Catherine E. Grant | First 5 Authors: Fabio Gastaldello, Martino Marelli, Silvano Molendi, Iacopo Bartalucci, Patrick Kühl | Summary: We analyzed the unexposed to the sky outFOV region of the MOS2 detector on board XMM-Newton covering 15 years of data amounting to 255 Ms. We show convincing evidence that the origin of the […]

The impact of galaxy selection on the splashback boundaries of galaxy clusters

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stephanie O’Neil, Josh Borrow, Mark Vogelsberger, Benedikt Diemer, | Summary: We explore how the splashback radius ($R_{rm sp}$) of galaxy clusters, measured using the number density of the subhalo population, changes based on various selection criteria using the IllustrisTNG cosmological galaxy formation simulation. We identify $R_{rm sp}$ […]

Predicting the Exoplanet Yield of the TESS Prime and Extended Missions Through Years 1-7

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Michelle Kunimoto, Joshua N. Winn, George R. Ricker, Roland Vanderspek, | Summary: The Transiting Exoplanet Survey Satellite (TESS) has discovered $sim$5000 planets and planet candidates after three and a half years of observations. With a planned second Extended Mission spanning Years 5 – 7 on the horizon, […]

Exceptional dynamics of interacting spin liquids

Kavli Affiliate: Frank Wilczek | First 5 Authors: Kang Yang, Daniel Varjas, Emil J. Bergholtz, Sid Morampudi, Frank Wilczek | Summary: We show that interactions in quantum spin liquids can result in non-Hermitian phenomenology that differs qualitatively from mean-field expectations. We demonstrate this in two prominent cases through the effects of phonons and disorder on […]

Detection of Cosmological 21 cm Emission with the Canadian Hydrogen Intensity Mapping Experiment

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Kevin Bandura, Tianyue Chen, Meiling Deng | Summary: We present a detection of 21-cm emission from large-scale structure (LSS) between redshift 0.78 and 1.43 made with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Radio observations acquired over 102 nights are used to construct […]
