From dawn till disk: Milky Way’s turbulent youth revealed by the APOGEE+Gaia data

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vasily Belokurov, Andrey Kravtsov, , , | Summary: We use accurate estimates of aluminium abundance provided as part of the APOGEE Data Release 17 and Gaia Early Data Release 3 astrometry to select a highly pure sample of stars with metallicity $-1.5lesssim {rm [Fe/H]}lesssim 0.5$ born in-situ […]

Snowmass White Paper: Micro- and Macro-Structure of Black Holes

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Iosif Bena, Emil J. Martinec, Samir D. Mathur, Nicholas P. Warner, | Summary: The black-hole information paradox provides a stringent test of would-be theories of quantum gravity. String theory has made significant progress toward a resolution of this paradox, and has led to the fuzzball and […]

Signature of Supersonic Turbulence in Galaxy Clusters

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Yu Qiu, Marie-Lou Gendron-Marsolais, Tamara Bogdanovic, Julie Hlavacek-Larrondo | Summary: The hot intracluster medium (ICM) is thought to be quiescent with low observed velocity dispersions. Surface brightness fluctuations of the ICM also suggest that its turbulence is subsonic with a Kolmogorov scaling relation, indicating that […]

Tidally Tilted Pulsations in HD 265435, a subdwarf B Star with a Close White Dwarf Companion

Kavli Affiliate: George Ricker | First 5 Authors: Rahul Jayaraman, Gerald Handler, Saul Rappaport, Jim Fuller, Donald W. Kurtz | Summary: Tidally tilted pulsators (TTPs) are an intriguing new class of oscillating stars in binary systems; in such stars, the pulsation axis coincides with the line of apsides, or semi-major axis, of the binary. All […]

Trouble in Paradox

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: Recent developments in holography have suggested a potential resolution to the black hole information paradox within the context of gravitational effective field theory. We emphasize the non-local nature of this proposed resolution, and highlight the ways in which […]

Surface Brightness Profile of Lyman-$α$ Halos out to 320 kpc in HETDEX

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Maja Lujan Niemeyer, Eiichiro Komatsu, Chris Byrohl, Dustin Davis, Maximilian Fabricius | Summary: We present the median-stacked Lyman-$alpha$ surface brightness profile of 968 spectroscopically selected Lyman-$alpha$ emitting galaxies (LAEs) at redshifts $1.9<z<3.5$ in the early data of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). The selected LAEs […]

TOI-1670 b and c: An Inner Sub-Neptune with an Outer Warm Jupiter Unlikely to have Originated from High-Eccentricity Migration

Kavli Affiliate: George R. Ricker | First 5 Authors: Quang H. Tran, Brendan P. Bowler, Michael Endl, William D. Cochran, Phillip J. MacQueen | Summary: We report the discovery of two transiting planets around the bright ($V=9.9$ mag) main sequence F7 star TOI-1670 by the Transiting Exoplanet Survey Satellite. TOI-1670 b is a sub-Neptune ($R_mathrm{b} […]

A Uniform Type Ia Supernova Distance Ladder with the Zwicky Transient Facility: Absolute Calibration Based on the Tip of the Red Giant Branch (TRGB) Method

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Suhail Dhawan, Ariel Goobar, Joel Johansson, In Sung Jang, Mickael Rigault | Summary: The current Cepheid-calibrated distance ladder measurement of $H_0$ is reported to be in tension with the values inferred from the cosmic microwave background (CMB), assuming standard model cosmology. However, the tip of the […]
