Translators of Galaxy Morphology Indicators between Observation and Simulation
(2023-06-06)
Based on the recent advancements in numerical simulations of galaxy formation, we anticipate the achievement of realistic models of galaxies in the near future. Morphology is the most basic and fundamental property of ...
The puzzle of the formation of T8 dwarf Ross 458c
(2023-06-01)
At the lowest masses, the distinction between brown dwarfs and giant exoplanets is often blurred and literature classifications rarely reflect the deuterium burning boundary. Atmospheric characterization may reveal the ...
VISIONS: The VISTA Star Formation Atlas
(2023-05-31)
VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Australis, Lupus, Ophiuchus, and Orion. The ...
Kinematics, Structure, and Mass Outflow Rates of Extreme Starburst Galactic Outflows
(2023-05-19)
We present results on the properties of extreme gas outflows in massive (M * ∼ 1011 M ⊙), compact, starburst (star formation rate, SFR∼ 200 M ⊙ yr−1) galaxies at z = 0.4–0.7 with very high star formation surface densities ...
The hyperluminous X‐ray source population
(2023-05-16)
We have recently published a catalog of 1843 candidate ultraluminous X‐ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross‐correlating recent serendipitous source catalogs from the ...
The Diffuse Ionized Gas Halo of the Large Magellanic Cloud
(2023-05-15)
The Large Magellanic Cloud (LMC) has an extensive Hα emission halo that traces an extended, warm ionized component of its interstellar medium. Using the Wisconsin Hα Mapper telescope, we present the first kinematic Hα ...
Relaxed blue ellipticals: accretion-driven stellar growth is a key evolutionary channel for low mass elliptical galaxies
(2023-04-30)
How elliptical galaxies form is a key question in observational cosmology. While the formation of massive ellipticals is strongly linked to mergers, the low mass (M⋆/M⊙ < 10^9.5 regime remains less well explored. In ...
Measuring the giant radio galaxy length distribution with the LoTSS
(2023-04-19)
Context. Many massive galaxies launch jets from the accretion disk of their central black hole, but only ∼103 instances are known in which the associated outflows form giant radio galaxies (GRGs, or giants): luminous ...
The Ionization and Dynamics of the Makani Galactic Wind
(2023-04-18)
The Makani galaxy hosts the poster child of a galactic wind on scales of the circumgalactic medium. It consists of a two-episode wind in which the slow, outer wind originated 400 Myr ago (Episode I; R I = 20 − 50 kpc) and ...
Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups
(2023-04-12)
We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching ...
