The Astrophysical JournalStar-forming galaxies on the main sequence (MS) are often regarded as a uniform population characterized by similar global star formation properties. However, there exists a diversity in galaxy morphologies at a fixed stellar mass and star formation rate.

Dark matter in ALFALFA galaxies
Astronomy & AstrophysicsAims. This paper aims to investigate the galaxy-halo connection using a large sample of individual galaxies with H I-integrated spectra. We determined their dark matter content by applying a dynamical method based on H I line widths measured with the ...

Candidate AGNs in Late-Type Galaxies
, 2008 We have assembled a sample of 64 late-type spiral galaxies (T types 6.0-9.0, corresponding to Hubble types Scd-Sm) with archival Chandra data. At a signal-to-noise (S/N) threshold of 3, we find 12 objects with X-ray point-source detections in close proximity with the optical or near-infrared position of the nucleus (median offset δ= 1.6"), suggestive ...

The Evolution of the Cold Gas Fraction in Nearby Clusters’ Ram-pressure-stripped Galaxies
The Astrophysical Journal, 2023 Cluster galaxies are affected by the surrounding environment, which influences, in particular, their gas, stellar content, and morphology. In particular, the ram pressure exerted by the intracluster medium promotes the formation of multiphase tails of ...

Dark Matter in Late-type Dwarf Galaxies
, 1998 Previous studies of dwarf irregular galaxies have mostly found that these systems have slowly rising rotation curves and that they are dominated by dark matter, even well within the optical disk. However, based on new observations and a different technique to derive rotation curves, we find that the rotation curves may be steeper and that dark matter ...

Probing the effect of the protocluster environment on galaxy morphology at z = 2.23
Astronomy & AstrophysicsContext. As galaxies evolve in dense cluster and protocluster environments, they interact and quench their star formation. This gradually transforms the dominant galaxy population from star-forming galaxies to quiescent red galaxies.

Minor-merger-induced Star Formation Rejuvenation in an Elliptical Radio-loud Quasar Host, 3C 59
The Astrophysical JournalWe report a rare case where an elliptical radio-loud quasar host, 3C 59, rejuvenates star formation activity through minor mergers with its nearby satellite galaxies.

H i Observations of Giant Low Surface Brightness Galaxies
The Astrophysical JournalGiant low surface brightness (gLSB) galaxies are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses, which can reach 10 ^12 M _⊙ .
