Molecular gas in normal late-type galaxies [PDF]
Astronomy and Astrophysics, 2002 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 Origin of Star Formation in Early-type Galaxies Inferred from Spatially Resolved Spectroscopy
The Astrophysical Journal, 2023 We investigate the origin of star formation activity in early-type galaxies with current star formation using spatially resolved spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory in the Sloan Digital Sky Survey (SDSS).

The Astronomical Journal, 2023 We assemble a catalog of 15424 nearby galaxies within 50 Mpc with consistent and homogenized mass, distance, and morphological type measurements. Our catalog combines galaxies from HyperLeda, the NASA-Sloan Atlas, and the Catalog of Local Volume Galaxies.

THE H I CONTENT OF LOCAL LATE-TYPE GALAXIES [PDF]
The Astrophysical Journal, 2011 We present a solid relationship between the neutral hydrogen (HI) disk mass and the stellar disk mass of late-type galaxies in the local universe. This relationship is derived by comparing the stellar disk mass function from the Sloan Digital Sky Survey and the HI mass function from the HI Parkes All Sky Survey (HIPASS).

CHARACTERISTICS OF SPIRAL ARMS IN LATE-TYPE GALAXIES [PDF]
The Astrophysical Journal, 2015 We have measured the positions of large numbers of H II regions in four nearly face-on, late-type, spiral galaxies: NGC 628 (M 74), NGC 1232, NGC 3184 and NGC 5194 (M 51). Fitting log-periodic spiral models to segments of each arm yields local estimates of spiral pitch angle and arm width.

Colour-magnitude relations of late-type galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We use a large sample of galaxies drawn from the Sloan Digital Sky Survey (SDSS) and Two Micro All Sky Survey (2MASS) to present Color-Magnitude Relations (CMRs) for late-type galaxies in both optical and optical-infrared bands. A sample from SDSS Data Release 4 (DR4) is selected to investigate the optical properties.

Clustercentric Distance or Local Density? It Depends on Galaxy Morphology
The Astrophysical Journal, 2023 Determining which between projected local density and distance from the cluster center plays a major role in regulating morphological fractions in clusters is a longstanding debate.

Quantitative Morphology of High-Redshift Galaxies Using GALEX Ultraviolet Images of Nearby Galaxies [PDF]
Journal of Astronomy and Space Sciences, 2017 We present simulations of the optical-band images of high-redshift galaxies utilizing 845 near-ultraviolet (NUV) images of nearby galaxies obtained through the Galaxy Evolution Explorer (GALEX). We compute the concentration (C), asymmetry (A), Gini (G),

On the Decline of Star Formation during the Evolution of Galaxies
The Astrophysical Journal, 2023 Cosmological simulations predict that during the evolution of galaxies, the specific star formation rate continuously decreases. In a previous study we showed that generally this is not caused by the galaxies running out of cold gas but rather a decrease
