Magnetic-Field Vector Maps of Nearby Spiral Galaxies
Galaxies, 2019 We present a method for determining the directions of magnetic-field vectors in a spiral galaxy using two synchrotron polarization maps, an optical image, and a velocity field.

Atmospheric Pressure and Molecular Cloud Formation in Early-type Galaxies
The Astrophysical Journal, 2023 A strong correlation between atmospheric pressure and molecular gas mass is found in central cluster galaxies and early-type galaxies. This trend and a similar trend with atmospheric gas density would naturally arise if the molecular clouds condensed ...

Multiple Mechanisms Quench Passive Spiral Galaxies [PDF]
, 2017 We examine the properties of a sample of 35 nearby passive spiral galaxies in order to determine their dominant quenching mechanism(s). All five low mass ($\textrm{M}_{\star} < 1 \times 10^{10} \textrm{M}_{\odot}$) passive spiral galaxies are located in the rich Virgo cluster.

A multi-wavelength study of spiral structure in galaxies. I. General characteristics in the optical [PDF]
, 2020 Different spiral generation mechanisms are expected to produce different morphological and kinematic features. In this first paper in a series we carefully study the parameters of spiral structure in 155 face-on spiral galaxies, selected from the Sloan Digital Sky Survey, in the three $gri$ bands.

Subarcminute Localization of 13 Repeating Fast Radio Bursts Detected by CHIME/FRB
The Astrophysical Journal, 2023 We report on improved sky localizations of 13 repeating fast radio bursts (FRBs) discovered by CHIME/FRB via the use of interferometric techniques on channelized voltages from the telescope.

Multi‐Modal Instrument Performances (MMIP): A Musical Database
Computer Graphics Forum, EarlyView.Abstract Musical instrument performances are multimodal creative art forms that integrate audiovisual elements, resulting from musicians' interactions with instruments through body movements, finger actions, and facial expressions. Digitizing such performances for archiving, streaming, analysis, or synthesis requires capturing every element that shapes

Stellar Populations in Spiral Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 We report preliminary results of the characterization of bulge and inner disk stellar populations for 8 nearby spiral galaxies using Gemini/GMOS. The long-slit spectra extend out to 1-2 disk scale lengths with S/N/Ang > 50. Two different model fitting techniques, absorption-line indices and full spectral synthesis, are found to weigh age ...

Color Differences between Clockwise and Counterclockwise Spiral Galaxies [PDF]
arXiv, 2013 While spiral galaxies observed from Earth clearly seem to spin in different directions, little is yet known about other differences between galaxies that spin clockwise and galaxies that spin counterclockwise. Here we compared the color of 64,399 spiral galaxies that spin clockwise to 63,215 spiral galaxies that spin counterclockwise.
