Dynamics of Molecular Gas in the Central Region of the Quasar I Zwicky 1

The Astrophysical Journal, 2023
We present a study of the molecular gas distribution and kinematics in the cicumnuclear region (radii ≲2 kpc) of the z ≈ 0.061 quasar I Zwicky 1 using a collection of available Atacama Large Millimeter/submillimeter Array observations of the carbon ...

KINEMATICS OF STELLAR POPULATIONS IN POSTSTARBURST GALAXIES [PDF]

The Astrophysical Journal, 2015
Post-starburst galaxies host a population of early-type stars (A or F), but simultaneously lack indicators of ongoing star formation such as OII emission. Two distinct stellar populations have been identified in these systems: a young post-starburst population superimposed on an older host population.

SunRISE Ground Radio Lab: Monitoring Solar Radio Bursts With an Expansive Array of Antennae at High Schools Nationwide

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract The Sun Radio Interferometer Space Experiment (SunRISE) Ground Radio Lab (GRL) is a Science, Technology, Engineering, Arts, and Mathematics (STEAM) project, sponsored by NASA's SunRISE mission and organized by the University of Michigan College of Engineering. The project aims to engage and train the next generations of scholars.

When is a Bulge Not a Bulge? Revealing the Satellite Nature of NGC 5474’s Bulge

The Astrophysical Journal
A satellite galaxy of the nearby spiral M101, NGC 5474 has a prominent bulge offset from the kinematic center of the underlying star-forming disk that has gained attention in recent years.

Temporal Dynamics With and Without a Nervous System: Plant Physiology, Communication, and Movement

Cognitive Science, Volume 49, Issue 6, June 2025.
Abstract The concept of time has long been the subject of complex philosophical reflections and scientific research, which have interpreted it differently based on the starting question, context, and level of analysis of the system under investigation.

On the Origin of the Variety of Velocity Dispersion Profiles of Galaxies

The Astrophysical Journal
Observed and simulated galaxies exhibit a significant variation in their velocity dispersion profiles. We examine the inner and outer slopes of stellar velocity dispersion profiles using integral field spectroscopy data from two surveys, SAMI (for z < 0 ...

Evidence for Large-scale, Rapid Gas Inflows in z ∼ 2 Star-forming Disks

The Astrophysical Journal, 2023
We report high-quality H α /CO imaging spectroscopy of nine massive (log median stellar mass = 10.65 M _⊙ ) disk galaxies on the star-forming main sequence (henceforth SFGs), near the peak of cosmic galaxy evolution ( z ∼ 1.1–2.5), taken with the ESO ...

Modern Techniques in Galaxy Kinematics: Results from Planetary Nebula Spectroscopy [PDF]

Symposium - International Astronomical Union, 2003
We have observed planetary nebulae (PNe) in several early-type galaxies using new techniques on 4- to 8-meter-class telescopes. We obtain the first large data sets (≳ 100 velocities each) of PN kinematics in galaxies at ≳ 15 Mpc, and present some preliminary dynamical results.

Multi‐Modal Instrument Performances (MMIP): A Musical Database

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
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

Role of Gaseous Disk in the Formation of the Spiral Structure of the Milky Way Galaxy

Open Astronomy, 2016
We use observational gaseous and stellar density distributions in the disk of the Milky Way (MW) galaxy together with the disk rotation curve and measured disk velocity dispersion to build collisionless and combined collisionless-gaseous equilibrium ...
