Adiabatic waveforms for extreme mass-ratio inspirals via multivoice decomposition in time and frequency

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Scott A. Hughes, Niels Warburton, Gaurav Khanna, Alvin J. K. Chua, Michael L. Katz | Summary: We compute adiabatic waveforms for extreme mass-ratio inspirals (EMRIs) by "stitching" together a long inspiral waveform from a sequence of waveform snapshots, each of which corresponds to a particular geodesic […]

Two Massive Jupiters in Eccentric Orbits from the TESS Full Frame Images

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Mma Ikwut-Ukwa, Joseph E. Rodriguez, Samuel N. Quinn, George Zhou, Andrew Vanderburg | Summary: We report the discovery of two short-period massive giant planets from NASA’s Transiting Exoplanet Survey Satellite (TESS). Both systems, TOI-558 (TIC 207110080) and TOI-559 (TIC 209459275), were identified from the 30-minute cadence […]

Substructure at High Speed II: The Local Escape Velocity and Milky Way Mass with Gaia DR2

Kavli Affiliate: Lina Necib | First 5 Authors: Lina Necib, Tongyan Lin, , , | Summary: Measuring the escape velocity of the Milky Way is critical in obtaining the mass of the Milky Way, understanding the dark matter velocity distribution, and building the dark matter density profile. In Necib $&$ Lin (2021), we introduced a […]

Improved Spatial Resolution Achieved by Chromatic Intensity Interferometry

Kavli Affiliate: Frank Wilczek | First 5 Authors: Lu-Chuan Liu, Luo-Yuan Qu, Cheng Wu, Jordan Cotler, Fei Ma | Summary: Interferometers are widely used in imaging technologies to achieve enhanced spatial resolution, but require that the incoming photons be indistinguishable. In previous work, we built and analyzed color erasure detectors which expand the scope of […]

Substructure at High Speed I: Inferring the Escape Velocity in the Presence of Kinematic Substructure

Kavli Affiliate: Lina Necib | First 5 Authors: Lina Necib, Tongyan Lin, , , | Summary: The local escape velocity provides valuable inputs to the mass profile of the Galaxy, and requires understanding the tail of the stellar speed distribution. Following Leonard $&$ Tremaine (1990), various works have since modeled the tail of the stellar […]

R-process-rich stellar streams in the Milky Way

Kavli Affiliate: Anna Frebel | First 5 Authors: Maude Gull, Anna Frebel, Karina Hinojosa, Ian U. Roederer, Alexander P. Ji | Summary: We present high-resolution Magellan/MIKE spectra of 22 bright ($9<V<13.5$) metal-poor stars ($-3.18<mbox{[Fe/H]}<-1.37$) in three different stellar streams, the Helmi debris stream, the Helmi trail stream, and the $omega$ Centauri progenitor stream. We augment […]

Hamiltonian Gotay-Nester-Hinds analysis of the parametrized unimodular extension of the Holst action

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, | Summary: We give a detailed account of the Hamiltonian GNH analysis of the parametrized unimodular extension of the Holst action. The purpose of the paper is to derive, through the clear geometric picture […]
