The Astrophysical JournalInfrared-luminous galaxies are important sites of stellar and black hole mass assembly at most redshifts. Their luminosities are often estimated by fitting spectral energy distribution (SED) models to near- to far-infrared data, but the dependence of ...

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers
Annalen der Physik, Volume 536, Issue 2, February 2024.Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Outflows in Infrared-Luminous Starbursts at z < 0.5. II. Analysis and Discussion
, 2005 We have performed an absorption-line survey of outflowing gas in 78 starburst-dominated, infrared-luminous galaxies. This is the largest study of superwinds at z < 3. Superwinds are found in almost all infrared-luminous galaxies, and changes in detection

The Astrophysical JournalWe present a study of a sample of 45 spectroscopically confirmed, UV luminous galaxies at z ∼ 6. They were selected as bright Lyman-break galaxies (LBGs) using deep multiband optical images in more than 2 deg ^2 of the sky, and subsequently identified ...

HST astrometry of the closest brown dwarfs‐II. Improved parameters and constraints on a third body
Astronomische Nachrichten, Volume 345, Issue 1, January 2024.Abstract Located at less than two pc away, Luhman 16 AB (WISE J104915.57‐531906.1) is the closest pair of brown dwarfs and the third closest “stellar” system to Earth. An exoplanet candidate in the Luhman 16 binary system was reported in 2017 based on a weak astrometric signature in the analysis of 12 HST epochs.

Searching for Dark Galaxies with H I Detection from the Arecibo Legacy Fast ALFA (ALFALFA) Survey
The Astrophysical Journal Supplement SeriesWe present a catalog of 142 dark galaxy candidates in a region covered by the Arecibo Legacy Fast ALFA (ALFALFA) survey. We start with 344 ALFALFA H i sources without optical counterparts and remove those that do not seem to have a dark galaxy origin. To

The Astrophysical JournalWe use the CN/CO intensity ratio to obtain the dense gas fraction, f _dense , for a sample of 16 ultraluminous and luminous infrared (IR) galaxies and compare f _dense with a suite of global galaxy properties.

MAMMOTH-Subaru. II. Diverse Populations of Circumgalactic Lyα Nebulae at Cosmic Noon
The Astrophysical Journal Supplement SeriesCircumgalactic Ly α nebulae are gaseous halos around galaxies exhibiting luminous extended Ly α emission. This work investigates Ly α nebulae from deep imaging of ∼12 deg ^2 sky, targeted by the MAMMOTH-Subaru survey.

The Astrophysical JournalWe introduce a novel model to spectroscopically constrain the mid-infrared (MIR) extinction/attenuation curve from 3–17 μ m, using polycyclic aromatic hydrocarbon (PAH) emission drawn from an AKARI–Spitzer extragalactic cross-archival data set. Currently
