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.

Probing the kinematics of early-type galaxy halos using planetary nebulae

, 2008
We present first results of a study of the halo kinematics for a sample of early type galaxies using planetary nebulae (PNe) as kinematical tracers. PNe allow to extend up to several effective radii (Re) the information from absorption line kinematics ...

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 ...

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

Origin of rotational kinematics in the globular cluster system of M31: A new clue to the bulge formation

, 2009
We propose that the rotational kinematics of the globular cluster system (GCS) in M31 can result from a past major merger event that could have formed its bulge component.

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.

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 ...
