Kavli Affiliate: Erin A. Kara | First 5 Authors: Y. Homayouni, Gerard A. Kriss, Gisella De Rosa, Rachel Plesha, Edward M. Cackett | Summary: An intensive reverberation mapping campaign on the Seyfert 1 galaxy Mrk817 using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) revealed significant variations in the response of the […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Riccardo Middei, Matteo Perri, Simonetta Puccetti, Ioannis Liodakis, Laura Di Gesu | Summary: The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consensus regarding jet emission processes, the particle […]
Kavli Affiliate: Lina Necib | First 5 Authors: Danny Horta, Emily C. Cunningham, Robyn Sanderson, Kathryn V. Johnston, Alis Deason | Summary: Observational studies are finding stars believed to be relics of the earliest stages of hierarchical mass assembly of the Galaxy. In this work, we contextualize these findings by studying the masses, ages, spatial […]

Kavli Affiliate: Michael McDonald | First 5 Authors: Ben Forrest, Brian C. Lemaux, Ekta Shah, Priti Staab, Ian McConachie | Summary: Motivated by spectroscopic confirmation of three overdense regions in the COSMOS field at $zsim3.35$, we analyze the uniquely deep multi-wavelength photometry and extensive spectroscopy available in the field to identify any further related structure. […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Honggeun Kim, Nicholas S. Kern, Jacqueline N. Hewitt, Bang D. Nhan, Joshua S. Dillon | Summary: One key challenge in detecting 21 cm cosmological signal at z > 6 is to separate the cosmological signal from foreground emission. This can be studied in a power spectrum […]

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lorenzo Speri, Michael L. Katz, Alvin J. K. Chua, Scott A. Hughes, Niels Warburton | Summary: Extreme Mass Ratio Inspirals (EMRIs) are one of the key sources for future space-based gravitational wave interferometers. Measurements of EMRI gravitational waves are expected to determine the characteristics of their […]
