Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Luis Welbanks, Lucas Ellerbroek, William Bains, Janusz J. Petkowski | Summary: The search for signs of life in the Universe has entered a new phase with the advent of the James Webb Space Telescope (JWST). Detecting biosignature gases via exoplanet atmosphere transmission spectroscopy is in […]
Kavli Affiliate: Peter Graham | First 5 Authors: Jim Alexander, Vassilis Anastassopoulos, Gigor Atoian, Rick Baartman, Stefan Baeßler | Summary: The Proton EDM Experiment (pEDM) is the first direct search for the proton electric dipole moment (EDM) with the aim of being the first experiment to probe the Standard Model (SM) prediction of any particle […]

Kavli Affiliate: Gabor Furesz | First 5 Authors: Danielle Frostig, Viraj R. Karambelkar, Robert D. Stein, Nathan P. Lourie, Mansi M. Kasliwal | Summary: We present near-infrared follow-up observations of the International Gravitational Wave Network (IGWN) event S250206dm with the Wide-Field Infrared Transient Explorer (WINTER). WINTER is a near-infrared time-domain survey designed for electromagnetic follow-up […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Asher Berlin, Joshua W. Foster, Dan Hooper, Gordan Krnjaic, | Summary: We present a mechanism that allows thermal relic dark matter to annihilate efficiently in the Galactic Halo and in galaxy clusters, but not in the lower-velocity environments of dwarf spheroidal (dSph) galaxies. We realize this within […]
Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Brian P. Powell, Guillermo Torres, Veselin B. Kostov, Tamás Borkovits, Saul A. Rappaport | Summary: We present the discovery of two quadruple star systems — TIC 285853156 and TIC 392229331 — each consisting of two bound eclipsing binary stars. Among the most compact quadruples known, TIC […]
Kavli Affiliate: Tom Melia | First 5 Authors: Yu Watanabe, Shigeki Matsumoto, Christopher M. Karwin, Tom Melia, Michela Negro | Summary: Light weakly interacting massive particles (WIMPs), whose masses are in the sub-GeV scale, have been attracting more attention due to the negative results searching for traditional WIMPs. The light WIMPs are expected to produce […]
Shubo Li, Ran Li, Kaihao Wang, Zixiang Jia, Xiaoyue Cao | Summary: [[{“value”:”Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be a extremely compact, dark perturber in the well-known lensing system SDSSJ0946+1006 (the "Jackpot"). Its remarkable compactness challenges the standard cold dark matter (CDM) paradigm. In this paper, […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Christian Aganze, Vedant Chandra, Risa H. Wechsler, Ting S. Li, Sergey E. Koposov | Summary: The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey (with […]
