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 […]
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 […]
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 […]
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 […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Nathan P. Lourie, John W. Baker, Richard S. Burruss, Mark Egan, Gábor Fűrész | Summary: The Wide-Field Infrared Transient Explorer (WINTER) is a new infrared time-domain survey instrument which will be deployed on a dedicated 1 meter robotic telescope at Palomar Observatory. WINTER will perform a seeing-limited […]

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 […]
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 […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nicolas F. Bouché, Shy Genel, Alisson Pellissier, Cédric Dubois, Thierry Contini | Summary: We investigate the specific angular momentum (sAM) $ j(<r)$ profiles of intermediate redshift ($0.4<z<1.4$) star-forming galaxies (SFGs) in the relatively unexplored regime of low masses (down to $M_starsim 10^8$M$_{odot}$), and small sizes (down to […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Tolga Guver, Tugba Boztepe, Ersin Gogus, Manoneeta Chakraborty, Tod E. Strohmayer | Summary: We report the temporal and spectral analysis of three thermonuclear X-ray bursts from 4U 1608-52, observed by the Neutron Star Interior Composition Explorer (NICER) during and just after the outburst observed from the source […]
