Asymmetry is a common trait in spiral galaxies and is particularly frequent among Magellanic spirals. To explore how morphological and kinematic asymmetry are affected by companion galaxies, we analyze neutral hydrogen observations of the interacting Magellanic spirals NGC 4618 and NGC 4625. The analysis of the H I distribution reveals that about 10% of the total H I mass of NGC 4618 resides in a looping tidal structure that appears to wrap all the way around the galaxy. Through calculations… 
We present a detailed analysis of high-resolution H i observations of the Magellanic spiral galaxies NGC 4618 and NGC 4625. While the H i disk of NGC 4625 is remarkably quiescent with a nearly
Recent far-UV (FUV) and near-UV (NUV) observations of the nearby galaxy NGC 4625 made by the Galaxy Evolution Explorer (GALEX) show the presence of an extended UV disk reaching to 4 times the optical
Chemical and Photometric Evolution of Extended Ultraviolet Disks: Optical Spectroscopy of M83 (NGC 5236) and NGC 4625*
We present the results from the analysis of optical spectra of 31 Hα-selected regions in the extended UV (XUV) disks of M83 (NGC 5236) and NGC 4625 recently discovered by GALEX. The spectra were
Testing the Molecular-Hydrogen Kennicutt-Schmidt Law in the Low-Density Environments of Extended Ultraviolet Disk Galaxies
Studying star formation beyond the optical radius of galaxies allows us to test empirical relations in extreme conditions with low average gas density and low molecular fraction. Previous studies
Optical BVI Imaging and HI Synthesis Observations of the Dwarf Irregular Galaxy ESO 364-G 029
As part of an effort to enlarge the number of well-studied Magellanic-type galaxies, we obtained broadband optical imaging and neutral hydrogen radio synthesis observations of the dwarf irregular
On The Extended Knotted Disks of Galaxies
The stellar disks of many spiral galaxies are twice as large as generally thought. We use archival data from the Galaxy Evolution Explorer mission to quantify the statistical properties of young
Spin Parity of Spiral Galaxies. I. Corroborative Evidence for Trailing Spirals
Whether the spiral structure of galaxies is trailing or leading has been a subject of debate. We present a new spin parity catalog of 146 spiral galaxies that lists the following three pieces of
Tidal-induced lopsidedness in Magellanic-type galaxies
We investigate the tidally-induced conversion of barred late-type spirals to Magellanic-type discs with numerical simulations, to establish how the lifetime of lopsidedness (asymmetry) varies with
Simulations of XUV Disks with a Star Formation Density Threshold
The outer regions of disk galaxies show a drop-off in optical and Hα emission, suggesting a star formation threshold radius, assumed to owe to a critical surface density below which star formation
On the nature of the H ii regions in the extended ultraviolet disc of NGC 4625
Using deep Subaru/Faint Object Camera And Spectrograph (FOCAS) spectra of 34 H II regions in both the inner and outer parts of the extended ultraviolet (XUV) disc galaxy NGC 4625 we have measured an


The Nature of the Extended H I Gas around NGC 4449: The Dr. Jekyll/Mr. Hyde of Irregular Galaxies
We present interferometric H I 21 cm line observations of the extended gas around the irregular galaxy NGC 4449 covering 67' on the sky at a resolution of ~1'. The main star-forming body of NGC 4449
Properties of the Magellanic-Type Spirals. I. Surface Photometry of NGC 4618 and NGC 4625
CCD and photographic BVRI broadband surface photometric observations obtained at McDonald Observatory, Capilla Peak Observatory, Asiago Observatory, and with the 2.1-m Struve reflector during the
Dynamical Modeling of NGC 7252 and the Return of Tidal Material
Motivated by recent neutral hydrogen observations with the VLA, we have undertaken an investigation into the interaction that produced the well known merger remnant NGC 7252. Through fully
Using tidal tails to probe dark matter halos
We use simulations of merging galaxies to explore the sensitivity of the morphology of tidal tails to variations of the halo mass distributions in the parent galaxies. Our goal is to constrain the
The kinematics of lopsided galaxies
Lopsidedness is a common feature in galaxies, both in the distribution of light and in the kinematics. We investigate the kinematics of a model for lopsided galaxies that consists of a disc lying
Lopsided Spiral Galaxies and a Limit on the Galaxy Accretion Rate
We present a measurement of lopsidedness for the stellar disks of 60 field spiral galaxies in terms of the azimuthal m = 1 Fourier amplitude, A1, of the stellar light. We confirm the previous result
Kinematically lopsided spiral galaxies
Asymmetries in the distribution of light and neutral hydrogen are often observed in spiral galaxies, Here, attention is drawn to the presence of large-scale asymmetries in their kinematics. Two
Quantifying the Fragility of Galactic Disks in Minor Mergers
We perform fully self-consistent stellar dynamical simulations of the accretion of a companion ("satellite") galaxy by a large disk galaxy to investigate the interaction between the disk, halo, and
Formation of shells in major mergers
Numerical simulations are used to study the fate of disks in mergers between equal-mass galaxies. Contrary to popular belief, mergers between equal-mass galaxies can form shells, loops, and ripples.
A Model for Lopsided Galactic Disks
Many disk galaxies are lopsided; their brightest inner parts are displaced from the center of the outer isophotes or the outer contours of the H I disk. This asymmetry is particularly common in
