Double-barred galaxies

, 2004
I present a catalog of 67 barred galaxies which contain distinct, elliptical stellar structures inside their bars. Fifty of these are double-barred galaxies: a small-scale, inner or secondary bar is embedded within a large-scale, outer or primary bar.

Rotation curves and dynamical masses of MaNGA barred galaxies

, 2023
In this paper we analyse a sample of 46 barred galaxies of MaNGA. Our goal is to investigate the stellar kinematics of these galaxies and obtain their rotation curves.

Mapping the Active Galactic Nucleus Effects on the Stellar and Gas Properties of NGC 5806

The Astrophysical Journal
It is commonly accepted that active galactic nuclei (AGNs) have a strong impact upon the evolution of their host galaxies, but the processes by which they do so are not fully understood.

Bars and the symmetry of star formation patterns in the discs of spiral galaxies

, 1998
We present a test for the degree of symmetry in the distribution of the Hα brightness along the arms of a sample of spiral galaxies. The test consists of deriving the cross-correlation function of the Hα brightness as a function of curvilinear distance ...

ALMA-LEGUS. I. The Influence of Galaxy Morphology on Molecular Cloud Properties

The Astrophysical Journal
We present a comparative study of the molecular gas in two galaxies from the Legacy ExtraGalactic UV Survey (LEGUS) sample: barred spiral NGC 1313 and flocculent spiral NGC 7793.

Orbital Classification in Rotating Bar Potentials Using an Empirical Proxy of the Second Integral of Motion

The Astrophysical Journal
We present a novel method for classifying two-dimensional orbits in rotating bar potentials based on an empirical proxy for the second integral of motion, calibrated angular momentum (CAM), which is defined as the ratio of the time-averaged angular ...
