The Chemodynamics of the Stellar Populations in M31 from APOGEE Integrated-light Spectroscopy
The Astrophysical Journal, 2023 We present an analysis of nearly 1000 near-infrared, integrated-light spectra from APOGEE in the inner ∼7 kpc of M31. We utilize full-spectrum fitting with A-LIST simple stellar population spectral templates that represent a population of stars with the ...

The first detection of Far-Infrared emission associated with an extended HI disk. The case of NGC 891 [PDF]
, 2003 Spiral galaxies in the Local Universe are commonly observed to be embedded in extended disks of neutral hydrogen - the so called ``extended HI disks''.

Disk Galaxies at High Redshift? [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe successful implementation of integral field near-infrared spectrographs fed by adaptive optics is providing unprecedented views of gas motions within galaxies at redshifts z = 2 − 3, when the universe was forming stars at its peak rate. A complex picture of galaxy kinematics is emerging, with inflows, rotation within sometimes extended and ...

The Astrophysical Journal Supplement Series, 2023 In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on the evolution of protoplanetary disks orbiting around nearby young stars ...

Dynamical Stability and Environmental Influences in Low Surface Brightness Disk Galaxies [PDF]
, 1996 Using analytic stability criteria, we demonstrate that, due to their low surface mass density and large dark matter content, LSB disks are quite stable against the growth of global nonaxisymmetric modes such as bars.

Circumnuclear Keplerian Disks in Galaxies
The Astrophysical Journal, 1998 In this paper we demonstrate the possibility of inferring the presence of Keplerian gaseous disks using optical ground-based telescopes properly equipped. We have modeled the peculiar bidimensional shape of the emission lines in a sample of five S0-Sa galaxies as due to the motion of a gaseous disk rotating in the combined potential of a central point ...

HI Observations of Interacting Galaxy Pair NGC 4038/9 [PDF]
, 2001 We present the results of new radio interferometer HI line observations for the merging galaxy pair NGC 4038/9 (`The Antennae'), obtained using the Australia Telescope Compact Array.
