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 […]

The MUSE Hubble Ultra Deep Field Survey XVI. The angular momentum of low-mass star-forming galaxies. A cautionary tale and insights from TNG50

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 […]
