The Metallicity and Distance of Leo A from Blue Supergiants
The Astrophysical Journal, 2023 We have obtained high-quality spectra of blue supergiant candidates in the dwarf irregular galaxy Leo A with the Low Resolution Imaging Spectrometer at the Keck I telescope.

THE STELLAR MASS CONTENT OF SUBMILLIMETER-SELECTED GALAXIES [PDF]
The Astrophysical Journal, 2011 We present a new study of the stellar mass in a sample of ~ 70 submillimeter-selected galaxies (SMGs) with accurate spectroscopic redshifts. We fit combinations of stellar population synthesis models and power laws to the galaxies' observed-frame optical through mid-IR spectral energy distributions to separate stellar emission from non-stellar near-IR ...

The Astronomical Journal, 2023 Stellar kinematics and metallicity are key to exploring formation scenarios for galactic disks and halos. In this work, we characterized the relationship between kinematics and photometric metallicity along the line of sight to M31's disk.

The Stellar Content of Active Galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We present results of a long-slit spectroscopic study of 39 active and 3 normal galaxies. Stellar absorption features, continuum colors and their radial variations are analyzed in an effort to characterize the stellar population in these galaxies and detect the presence of a featureless continuum underlying the starlight spectral component.

Robust Data-driven Metallicities for 175 Million Stars from Gaia XP Spectra
The Astrophysical Journal Supplement Series, 2023 We derive and publish data-driven estimates of stellar metallicity [M/H] for ∼175 million stars with low-resolution XP spectra published in Gaia DR3.

Formation of Transitional cE/UCD Galaxies through Massive/Dwarf Disc Galaxy Mergers
Galaxies, 2023 The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky Way type were studied in detail. The remnant of such interaction after numerous crossings of the satellite through the disc of the main galaxy was a compact ...

The Stellar Content of 10 Dwarf Irregular Galaxies [PDF]
The Astronomical Journal, 1998 We examine the stellar content of 10 dwarf irregular galaxies of which broad-band CCD photometry was published in Hopp & Schulte-Ladbeck (1995). We also present Halpha images for several of these galaxies. The galaxies in the sample are located outside of the Local Group.

The Progenitor of the Peculiar Galaxy NGC 3077
The Astrophysical Journal, 2023 We present a study of the structural properties and metallicity distribution of the nearby peculiar galaxy NGC 3077. Using data from our survey of the M81 Group with the Hyper Suprime-Cam on board the Subaru Telescope, we construct deep color–magnitude ...

The Origin of the Nuclear Star-forming Ring in NGC 3182
The Astronomical Journal, 2023 We investigate the stellar and ionized gas kinematics, and stellar populations of NGC 3182 galaxy using integral field spectrograph data from the Calar Alto Legacy Integral Field Area survey. We try to clarify the nature of the ring structure in NGC 3182.

Structure and stellar content of dwarf galaxies [PDF]
Astronomy & Astrophysics, 2001 CCD photometry in the Cousins B , V and R bands of 19 northern field dwarf galaxies is presented. For each galaxy, and for each colour, we determined total magnitude, effective radius and effective surface brightness, and, by fitting an exponential to the surface brightness profile, central surface brightness and exponential scale length.
