Moderate-Resolution $K$-Band Spectroscopy of the Substellar Companion VHS 1256 b

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kielan K. W. Hoch, Quinn M. Konopacky, Travis S. Barman, Christopher A. Theissen, Laci Brock | Summary: We present moderate-resolution ($Rsim4000$) $K$ band spectra of the planetary-mass companion VHS 1256 b. The data were taken with the OSIRIS integral field spectrograph at the W.M. Keck Observatory. The […]

Object-centered population coding in CA1 of the hippocampus

Kavli Affiliate: Edvard Moser, May-Britt Moser | Authors: Anne Nagelhus, Sebastian Andersson, Soledad Gonzalo Cogno, Edvard I. Moser and May-Britt Moser | Summary: Objects and landmarks are crucial for guiding navigation and must be integrated into the cognitive map of space. Studies of object coding in the hippocampus have primarily focused on activity of single […]

Absolute Flux Calibrations for the Nancy Grace Roman Space Telescope Coronagraph Instrument

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Lindsey Payne, Robert T. Zellem, Marie Ygouf, Bruce Macintosh, | Summary: The Nancy Grace Roman Space Telescope’s (Roman) Coronagraph Instrument is a technology demonstration equipped to achieve flux contrast levels of up to 10$^{-9}$. This precision depends upon the quality of observations and their resultant on-sky corrections […]

Metal Mixing in the R-Process Enhanced Ultra-Faint Dwarf Galaxy Reticulum II

Kavli Affiliate: Anna Frebel | First 5 Authors: Alexander P. Ji, Joshua D. Simon, Ian U. Roederer, Ekaterina Magg, Anna Frebel | Summary: The ultra-faint dwarf galaxy Reticulum~II was enriched by a single rare and prolific r-process event. The r-process content of Reticulum~II thus provides a unique opportunity to study metal mixing in a relic […]

LyC escape from SPHINX galaxies in the Epoch of Reionization

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Joakim Rosdahl, Jérémy Blaizot, Harley Katz, Taysun Kimm, Thibault Garel | Summary: We measure escape fractions, $f_{rm esc}$, of ionizing radiation from galaxies in the SPHINX suite of cosmological radiation-hydrodynamical simulations of reionization, resolving halos with $M_{rm vir} gtrapprox 7.5 times 10^7 M_{odot}$ with a minimum cell […]

The Atacama Cosmology Telescope: The Persistence of Neutrino Self-Interaction in Cosmological Measurements

Kavli Affiliate: David N. Spergel | First 5 Authors: Christina D. Kreisch, Minsu Park, Erminia Calabrese, Francis-Yan Cyr-Racine, Rui An | Summary: We use data from the Atacama Cosmology Telescope (ACT) DR4 to search for the presence of neutrino self-interaction in the cosmic microwave background. Consistent with prior works, the posterior distributions we find are […]
