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

Posted by klaurent Peking

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

Posted by klaurent Chicago

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 […]

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

Posted by klaurent MIT

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

Posted by klaurent Chicago

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

Posted by klaurent UCSF

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 […]

A preparative mass spectrometer to deposit intact large native protein complexes

Posted by klaurent Oxford

Kavli Affiliate: Stephan Rauschenbach | Summary:Electrospray ion-beam deposition (ES-IBD) is a versatile tool to study structure and reactivity of molecules from small metal clusters to large protein assemblies. It brings molecules gently into the gas phase where they can be accurately manipulated and purified, followed by controlled deposition onto various substrates. In combination with imaging […]

Unsupervised learning of two-component nematicity from STM data on magic angle bilayer graphene

Posted by klaurent Caltech

Kavli Affiliate: Stevan Nadj-Perge | Summary:Moiré materials such as magic angle twisted bilayer graphene (MATBG) exhibit remarkable phenomenology, but present significant challenges for certain experimental methods, particularly scanning probes such as scanning tunneling microscopy (STM). Typical STM studies that can image tens of thousands of atomic unit cells can image roughly ten moiré cells, making […]

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

Posted by klaurent MIT

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

Posted by Chicago

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 cosmology. However, some tip of the red […]
