Kavli Affiliate: Anna Frebel | First 5 Authors: Terese T. Hansen, Ian U. Roederer, Shivani P. Shah, Rana Ezzeddine, Timothy C. Beers | Summary: Context. Over the past few years, the $R$-Process Alliance (RPA) has successfully carried out a search for stars that are highly enhanced in elements produced via the rapid neutron-capture ($r$-) process. […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ruth M. E. Kelly, Herman L. Marshall, Silvia Zane, Nabil Brice, Swati Ravi | Summary: X-ray polarimetry offers a unique window into neutron star physics and can provide answers to questions that cannot otherwise be probed. The up-and-coming REDSoX sounding rocket mission will be the first […]
Kavli Affiliate: Erin Kara | First 5 Authors: Christos Panagiotou, Iossif Papadakis, Erin Kara, Marios Papoutsis, Edward M. Cackett | Summary: Over the last years, a number of broadband reverberation mapping campaigns have been conducted to explore the short-term UV and optical variability of nearby AGN. Despite the extensive data collected, the origin of the […]
Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Kishalay De, Christos Panagiotou, Erin Kara, Anna-Christina Eilers | Summary: Mid-infrared (MIR) emission from tidal disruption events (TDEs) is a powerful probe of the circumnuclear environment around dormant supermassive black holes. This emission arises from the reprocessing of intrinsic emission into thermal MIR emission by […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Lina Necib, Andrew Wetzel, Anna Frebel, Jeremy Bailin | Summary: Recent measurements of the Milky Way rotation curve found a sharp decline at around $15$-$20$ kpc from the center of the Galaxy, suggesting that the Galactic dark matter halo is much less massive than predicted […]
Kavli Affiliate: Sara Seager | First 5 Authors: Elina Y. Zhang, Theron W. Carmichael, Daniel Huber, Keivan G. Stassun, Akihiko Fukui | Summary: As the intermediate-mass siblings of stars and planets, brown dwarfs (BDs) are vital to study for a better understanding of how objects change across the planet-to-star mass range. Here, we report two […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William McClymont, Sandro Tacchella, Aaron Smith, Rahul Kannan, Ewald Puchwein | Summary: We explore the evolution of galaxy sizes at high redshift ($3 < z < 13$) using the high-resolution THESAN-ZOOM radiation-hydrodynamics simulations, focusing on the mass range of $10^6,mathrm{M}_{odot} < mathrm{M}_{ast} < 10^{10},mathrm{M}_{odot}$. Our analysis reveals […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Gerrit Schellenberger, Ralph Kraft, Paul Nulsen, Eric D. Miller, Marshall W. Bautz | Summary: The level and uncertainty of the particle induced background in CCD detectors plays a crucial role for future X-ray instruments, such as the Wide Field Imager (WFI) onboard Athena. To mitigate the […]
