Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon, Dheeraj R. Pasham, | Summary: Some electromagnetic outbursts from the nuclei of distant galaxies have been found to repeat on months-to-years timescales, and each of these sources can putatively arise from the accretion flares generated through the repeated […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, Timothy C. Beers, Kohei Hattori, Vinicius M. Placco, Terese T. Hansen | Summary: We present stellar parameters and chemical abundances of 47 elements detected in the bright (V = 11.63) very metal-poor ([Fe/H] = -2.20 +- 0.12) star 2MASS J22132050-5137385. We observed this star […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Melinda Soares-Furtado, Mary Anne Limbach, Andrew Vanderburg, John Bally, Juliette Becker | Summary: The TEMPO (Transiting Exosatellites, Moons, and Planets in Orion) Survey is a proposed 30-day observational campaign using the Nancy Grace Roman Space Telescope. By providing deep, high-resolution, short-cadence infrared photometry of a dynamic star-forming […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Josh Borrow, Mark Vogelsberger, | Summary: We derive the central stellar velocity dispersion function for quiescent galaxies in 280 massive clusters with $log (M_{200} / M_{odot}) > 14$ in IllustrisTNG300. The velocity dispersion function is an independent tracer of the dark matter […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Yash Bhargava, Mason Ng, Liang Zhang, Arvind Balasubramanian, Thomas D. Russell | Summary: We present the discovery of X-ray polarization from the neutron star low-mass X-ray binary and Z-source, GX~340$+$0, using an Imaging X-ray Polarimetry Explorer (IXPE) observation in March 2024. Along with the IXPE observation, we […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Leon Shaposhnikov, Eduardo Barredo-Alamilla, Frank Wilczek, Maxim A. Gorlach, | Summary: Spatial structuring of materials at subwavelength scales underlies the concept of metamaterials possessing exotic properties beyond those of the constituent media. Temporal modulation of material parameters enables further functionalities. Here, we show that high-frequency oscillations of […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Xiaoman Delores Ding, Zifan Carl Guo, Eric J. Michaud, Ziming Liu, Max Tegmark | Summary: When a neural network can learn multiple distinct algorithms to solve a task, how does it "choose" between them during training? To approach this question, we take inspiration from ecology: when multiple […]
Kavli Affiliate: Ralf K. Heilmann | First 5 Authors: Ralf K. Heilmann, Alexander R. Bruccoleri, James A. Gregory, Eric M. Gullikson, Hans Moritz Günther | Summary: The Arcus Probe mission concept has been submitted as an Astrophysics Probe Explorer candidate. It features two co-aligned high-resolution grating spectrometers: one for the soft x-ray band and one […]
