Identification of Intermediate-mass Black Hole Candidates among a Sample of Sd Galaxies
The Astrophysical JournalWe analyzed images of every northern hemisphere Sd galaxy listed in the Third Reference Catalogue of Bright Galaxies with a relatively face-on inclination ( θ ≤ 30°). Specifically, we measured the spiral arms’ winding angle, ϕ , in 85 galaxies.

Molecular hydrogen in galaxies [PDF]
, 1987 This study aims to understand the key role played by molecular hydrogen in the evolution of galaxies, with a view to constraining its radial distribution in the Galaxy and the CO→H(_2) conversion factor α(_20).The star formation rate is shown to be ...

Escaping Ionizing Photons from Massive Spiral Galaxies at z ∼ 1
The Astrophysical JournalWe report the detection of Lyman continuum (LyC) photons from three massive ( M _* > 10 ^10 M _⊙ ) spiral galaxies at a redshift of nearly 1 in the AstroSat UV Deep Field South.

Examination of the Functional Form of the Light and Mass Distribution in Spiral Arms
GalaxiesSpiral arms are a common feature of local galaxies, but the exact form of the distribution of mass and light in them is not well known. In this work, we aim to measure this distribution as accurately as possible, focusing on individual spiral arms and ...

Stellar orbital dynamics of disk galaxies: I bars, II spiral arms.
, 2019 I. Bars We investigate regular and chaotic two-dimensional (2D) and three-dimensional (3D) orbits of stars in models of a galactic potential consisting of a disk, a halo, and a bar to find the origin of boxy components that are part of the bar or (almost)

DARK MATTER IN SPIRAL GALAXIES
, 1990 The Tully-Fisher relation is used to probe dark matter (DM) in the optical regions of spiral galaxies. By establishing it at several different isophotal radii in an appropriate sample of 58 galaxies with good B-band photometry and rotation curves, we ...
