, 2013 We calculate the stellar surface mass density (Sigma_*) and two-component (gas+stars) disk stability (Q_RW) for 25 late-type galaxies from the DiskMass Survey. These calculations are based on fits of a dynamical model to our ionized-gas and stellar kinematic data performed using a Markov Chain Monte Carlo sampling of the Bayesian posterior ...

Disk Galaxies and Galaxy Disks [PDF]
Publications of the Astronomical Society of the Pacific, 2000 The conference Galaxy Disks and Disk Galaxies, sponsored by the Vatican Observatory, was held in June 12-16, 2000 at the Pontifical Gregorian University, in Rome (Italy). The meeting hosted about 230 participants coming from 30 countries. The very full program consisted of 29 review papers, 34 invited talks, and more than 180 posters.

The Astrophysical Journal, 2023 A key question in galaxy evolution has been the importance of the apparent “clumpiness” of high-redshift galaxies. Until now, this property has been primarily investigated in rest-frame UV, limiting our understanding of their relevance.

Tilted Dark Halos Are Common and Long-lived, and Can Warp Galactic Disks
The Astrophysical Journal Letters, 2023 In the Lambda cold dark matter paradigm, the dark halo governs the gravitational potential within which a galaxy can form and evolve. In this Letter we show that the present-day inner ( r < 50 kpc) dark halo can be significantly misaligned with the ...

XUE: Molecular Inventory in the Inner Region of an Extremely Irradiated Protoplanetary Disk
The Astrophysical Journal Letters, 2023 We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, which focuses on the characterization of planet-forming disks in massive star-forming regions.

Galaxies, 2015 I discuss my latest observational data and ideas about decoupled gaseous subsystems in nearby lenticular galaxies. As an extreme case of inclined gaseous disks, I demonstrate a sample of inner polar disks, derive their incidence, about 10% among the ...

THE OUTER DISKS OF GALAXIES:“TO BE OR NOT TO BE TRUNCATED?” [PDF]
, 2007 We have in recent years come to view the outer parts of galaxies as having vital clues about their formation and evolution. Here, we would like to briefly present our results from a complete sample of nearby, late-type, spiral galaxies, using data from the SDSS survey, especially focused on the stellar light distribution in the outer disk.
