Molecular gas in late-type galaxies

open access: yes, 2001
We present $^{12}$CO(J=1--0) line observations of 22 low-luminosity spiral galaxies in the Virgo cluster. These data, together with 244 others available in the literature, allow us to build a large sample that we use to study the molecular gas properties of galaxies spanning a large range of morphological types and luminosities and belonging to ...

The Star Formation History of Late Type Galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
Abstract The combination of huge databases of galaxy spectra and advances in evolutionary synthesis models in the past few years has renewed interest in an old question: How to estimate the star formation history of a galaxy out of its integrated spectrum?

Observed Evidence for the Primordial Origin of Galaxy Sizes

open access: yesThe Astrophysical Journal
We present observational evidence supporting the scenario that the protogalactic angular momenta play an important role in molding the optical sizes of present galaxies. Analyzing the NASA-Sloan Atlas catalog in the redshift range of 0.02 ≤ z

New morpho-kinematic classification: The two-dimensional spatial distribution of stellar specific angular momentum in late-type galaxies

open access: yesAstronomy & Astrophysics
Aims. The two-dimensional spatial distribution of stellar specific angular momentum (sAM) within galaxies has never been analysed. We seek to identify the morpho-kinematics of this property and its correlation with the total stellar sAM (j★) and the ...

The X-Ray Binary-star Cluster Connection in Late-type Galaxies

open access: yesThe Astrophysical Journal, 2023
We conduct one of the largest systematic investigations of bright X-ray binaries (XRBs) in both young star clusters and ancient globular clusters (GCs) using a sample of six nearby star-forming galaxies.

Resolved Stellar Mass Estimation of Nearby Late-type Galaxies for the SPHEREx Era: Dependence on Stellar Population Synthesis Models

open access: yesThe Astronomical Journal
The upcoming all-sky infrared spectrophotometric SPHEREx mission is set to provide spatially resolved stellar mass maps of nearby galaxies, offering more detailed insights than integrated light observations.

Counting the Unseen. I. Nuclear Density Scaling Relations for Nucleated Galaxies

open access: yesThe Astronomical Journal
The volumetric rate of tidal disruption events (TDEs) encodes information on the still-unknown demographics of central massive black holes (MBHs) in low-mass galaxies (≲10 ^9 M _⊙ ).

FAST Ultra-Deep Survey (FUDS): The Star Formation Histories of FUDS0 Galaxies

open access: yesThe Astrophysical Journal Supplement Series
We present the ultraviolet, optical, and infrared counterparts of 128 galaxies detected in neutral hydrogen (H i ) in the FAST Ultra-Deep Survey (FUDS) field 0 (FUDS0).

Polar structures in late-type galaxies

open access: yes, 2014
A common point of view is that stable polar structures are mainly present in the E/S0 early-type galaxies lacking dense gas in their host disks. However, nuclear, as well as external polar rings and disks also exist in the late-type hosts, including gas-rich dwarf galaxies.
