Solo dwarfs I: survey introduction and first results for the Sagittarius dwarf irregular galaxy [PDF]

open access: yes, 2016
We introduce the Solitary Local Dwarfs Survey (Solo), a wide field photometric study targeting every isolated dwarf galaxy within 3 Mpc of the Milky Way.

Outlier Detection in the DESI Bright Galaxy Survey

open access: yesThe Astrophysical Journal Letters, 2023
We present an unsupervised search for outliers in the Bright Galaxy Survey (BGS) data set from the DESI Early Data Release. This analysis utilizes an autoencoder to compress galaxy spectra into a compact, redshift-invariant latent space, and a ...

Massive stars in the Sagittarius Dwarf Irregular Galaxy [PDF]

open access: yes, 2017
Low metallicity massive stars hold the key to interpret numerous processes in the past Universe including re-ionization, starburst galaxies, high-redshift supernovae and GRBs.

Searches for Extremely Metal-poor Galaxies Using Arecibo Legacy Fast ALFA–Selected Dwarf Galaxies

open access: yesThe Astrophysical Journal, 2023
We present a study of nearby dwarf galaxies selected from the Arecibo Legacy Fast ALFA (ALFALFA) blind H i survey. A primary goal of the project was to utilize a nonstandard selection method with the hope of detecting previously unrecognized extremely ...

Pavo: Discovery of a Star-forming Dwarf Galaxy Just Outside the Local Group

open access: yesThe Astrophysical Journal Letters, 2023
We report the discovery of Pavo, a faint ( M _V = −10.0), star-forming, irregular, and extremely isolated dwarf galaxy at D ≈ 2 Mpc. Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness

A state-of-the-art analysis of the dwarf irregular galaxy NGC 6822 [PDF]

open access: yes, 2014
We present a detailed photometric study of the dwarf irregular galaxy NGC 6822 aimed at investigating the properties of its stellar populations and, in particular, the presence of stellar radial gradients.

Disk Galaxies Are Self-similar: The Universality of the H i-to-Halo Mass Ratio for Isolated Disks

open access: yesThe Astrophysical Journal Letters, 2023
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.

DWARF IRREGULAR GALAXY LEO A: SUPRIME-CAM WIDE-FIELD STELLAR PHOTOMETRY [PDF]

open access: yes, 2014
We have surveyed a complete extent of Leo A—an apparently isolated gas-rich low-mass dwarf irregular galaxy in the Local Group. The B, V, and I passband CCD images (typical seeing ∼0.″8) were obtained with the Subaru Telescope equipped with the Suprime ...

Modelling H i distribution and kinematics in the edge-on dwarf irregular galaxy KK250 [PDF]

open access: yes, 2014
We model the observed vertical distribution of the neutral hydrogen (HI) in the faint (MB 13:7 mag) edge-on dwarf irregular galaxy KK250. Our model assumes that the galaxy consists of axi-symmetric, co-planar gas and stellar discs in the external force ...
