The Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era
Advances in Astronomy, 2013 A new generation of wide-field emission-line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas-phase emission in nearby late-type galaxies, based on large samples of HII regions and full two ...

The Extended Baryonic Tully–Fisher Relation for SDSS MaNGA Galaxies
The Astrophysical JournalThe baryonic Tully–Fisher relation (BTFR), a relationship between the rotational velocity and baryonic mass in spiral galaxies, probes the relative content of baryonic and total mass in galaxies and thus provides a good test of dark matter content in ...

Diverse reddening distributions in sight lines for type Ia supernovae
Astronomy & AstrophysicsContext. Accurate cosmological constraints from type Ia supernovae (SNe) require sufficiently accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the problem of disentangling the SN’s intrinsic colours from host ...

The Astrophysical Journal Supplement SeriesWe analyze a clean sample of 1118 late-type, face-on galaxies without active galactic nucleus contamination from the MaNGA survey. Their photometric structures are quantified via two-component (bulge + disk) decompositions of deep g -band images from the

SDSS-IV MaNGA: Spectroscopic Probes of Neutral Gas in Nearby Galaxies
The Astrophysical JournalCool, dusty interstellar material plays an important role in the chemical evolution of galaxies. We present an analysis of this material across galaxy type through a spatially resolved spectral stacking analysis of galaxies from the MaNGA survey.

Stellar mass and morphology segregation into pairs and multiplets in the cosmic web
Astronomy & AstrophysicsAims. In this work, we investigate whether the location of galaxies within the large-scale structures (LSS) of the Universe leaves an imprint on their stellar mass (M★) and morphology. To this end, we attempt to disentangle the effects of local and large-

A Morphological Study of AGN-host Dwarf Galaxies
The Astrophysical JournalThe study of morphology in galaxies offers a convenient and quantitative method to measure the shapes and characteristics of galaxy light distribution that reflect the evolutionary history.

The nature of late-type spiral galaxies
Monthly Notices of the Royal Astronomical Society, 2009 We analyse V-and H-band surface photometry of a sample of 18 Sb-Sd galaxies. Combining high-resolution Hubble Space Telescope (HST) images with ground-based near-infrared observations, we extract photometric profiles, which cover the whole disc and provide the highest possible resolution.

Luminosity Evolution of the Hot Gas in Normal Galaxies from the Near Universe to z = 0.5
The Astrophysical JournalWe explore the evolution of the ∼10 ^7 K hot gas in normal galaxies out to redshift = 0.5 (lookback time = 5 Gyr), using X-ray luminosity functions (XLFs) built from a sample of 575 normal galaxies with z < 0.6 detected in five high-galactic-latitude ...

Astronomy & AstrophysicsThe mass in the Universe is distributed non-uniformly, leading to the large scale structure (LSS), characterised by clusters, filaments, walls, and voids.
