The feasibility of constraining DM interactions with high-redshift observations by JWST

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ali Kurmus, Sownak Bose, Mark Lovell, Francis-Yan Cyr-Racine, Mark Vogelsberger | Summary: Observations of the high redshift universe provide a promising avenue for constraining the nature of the dark matter (DM). This will be even more true with the advent of the James Webb Space Telescope (JWST). […]

Signature of Supersonic Turbulence in Galaxy Clusters Revealed by AGN-driven H$α$ Filaments

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 […]

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 […]

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 […]

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 […]

Not optimal, just noisy: the geometry of correlated variability leads to highly suboptimal sensory coding

Kavli Affiliate: Kristofer Bouchard | Authors: Jesse A Livezey, Pratik Singh Sachdeva, Maximilian E Dougherty, Mathew T Summers and Kristofer E Bouchard | Summary: The brain represents the world through the activity of neural populations. Correlated variability across simultaneously recorded neurons (noise correlations) has been observed across cortical areas and experimental paradigms. Many studies have […]

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 […]
