Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: Recent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with DESI measurements of baryon acoustic […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yuan-Sen Ting, Alexander P. Ji, , , | Summary: Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than $sim$100 Myr should lead to discontinuous tracks in […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ashai Moreno, Vincent Chambouleyron, Rebecca M. Jensen-Clem, Daren Dillon, Philip M. Hinz | Summary: The Santa Cruz Extreme AO Lab (SEAL) testbed is an optical bench meant to design and develop new wavefront control techniques for high-contrast imaging for segmented telescopes. These techniques allow for astronomical efficiency […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Carlos Hervías-Caimapo, Ari J. Cukierman, Patricia Diego-Palazuelos, Kevin M. Huffenberger, Susan E. Clark | Summary: We extend the dust-filament-based model presented in Herv’ias-Caimapo & Huffenberger 2022 to produce parity-violating foreground spectra by manipulating the filament orientations relative to the magnetic field. We calibrate our model to […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, In Sung Jang, Taylor J. Hoyt, Abigail J. Lee | Summary: We present the latest results from the Chicago Carnegie Hubble Program (CCHP) to measure the Hubble constant using data from the James Webb Space Telescope (JWST). This program is […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Wen-Li Yuan, Bikai Gao, Yan Yan, Bolin Li, Renxin Xu | Summary: We extend the parity doublet model for hadronic matter and study the possible presence of quark matter inside the cores of neutron stars with the Nambu-Jona-Lasinio (NJL) model. Considering the uncertainties of the QCD phase […]
Kavli Affiliate: George Ricker | First 5 Authors: Ilaria Carleo, Oscar Barrágan, Carina M. Persson, Malcolm Fridlund, Kristine W. F. Lam | Summary: Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our understanding on their actual origin. The present […]

Kavli Affiliate: Erin Kara | First 5 Authors: Edward Nathan, Adam Ingram, James F. Steiner, Ole König, Thomas Dauser | Summary: The black hole X-ray binary H1743-322 lies in a region of the Galaxy with high extinction, and therefore it has not been possible to make a dynamical mass measurement. In this paper we make […]
