  • ELVES II: early-type satellites phot. & GC data

    We present the properties of the globular clusters (GCs) and nuclear star clusters (NSCs) of low-mass (10^5.5^<M_<10^8.5^M{sun}) early-type satellites of Milky Way-like...
  • Abundances of Sculptor dSph stars

    We demonstrate that using up to seven stellar abundance ratios can place observational constraints on the star formation histories (SFHs) of Local Group dSphs, using Sculptor...
  • Fornax stars M2FS spectroscopy with Gaia EDR3 data

    The Fornax dwarf spheroidal galaxy has an anomalous number of globular clusters, five, for its stellar mass. There is a longstanding debate about a potential sixth globular...
  • Dwarf galaxies photometry & structures

    The structure of a dwarf galaxy is an important probe of the effects of stellar feedback and environment. Using an unprecedented sample of 223 low-mass satellites from the...
  • [FeX]{lambda}6374 em. in SDSS dwarf galaxies

    The massive black hole (BH) population in dwarf galaxies (M_BH_<~10^5^M_{sun}) can provide strong constraints on the origin of BH seeds. However, traditional optical searches...
  • Kinematics of Ant2 & Cra2 with S5 (DR2.2) & Gaia data

    We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey...
  • VLT Spectroscopy of Ultra-faint Dwarf Galaxies

    We perform consistent reductions and measurements for three ultra-faint dwarf galaxies (UFDs): Bootes I, Leo IV, and Leo V. Using the public archival data from the GIRAFFE...
  • Variable Stars in Local Group Galaxies. VI.

    We present the discovery of variable stars in two isolated dwarf galaxies in the outskirts of the Local Group, VV 124 and KKr 25, using observations with the Hubble Space...
  • Satellites around MW analogs from SAGA II

    We compare the star-forming properties of satellites around Milky Way (MW) analogs from the Stage II release of the Satellites Around Galactic Analogs Survey (SAGA-II) to those...
  • CFHT dwarf satellite galaxies around LV hosts

    We present the results of an extensive search for dwarf satellite galaxies around 10 primary host galaxies in the Local Volume (LV, D<12Mpc) using archival CFHT/MegaCam...
  • NGFS. IV. The Fornax core region

    We present the analysis of 61 nucleated dwarf galaxies in the central regions (<~R_vir_/4) of the Fornax galaxy cluster. The galaxies and their nuclei are studied as part of...
  • High-EW [OIII] and H{alpha} emitters from 3D-HST

    The multiplexing capability of slitless spectroscopy is a powerful asset in creating large spectroscopic data sets, but issues such as spectral confusion make the interpretation...
  • Variable stars in the NIR in nearby galaxies. I.

    The Draco Dwarf spheroidal (dSph) galaxy is one of the nearest and the most dark-matter-dominated satellites of the Milky Way. We obtained multiepoch near-infrared (NIR, JHKs)...
  • Stellar population in Cassiopeia III and Perseus I

    We present results from wide-field imaging of the resolved stellar populations of the dwarf spheroidal galaxies CassiopeiaIII (AndXXXII) and PerseusI (AndXXXIII), two satellites...
  • SFACT. III. SFF01 -10 and -15 spectral data

    The Star Formation Across Cosmic Time (SFACT) survey is a new narrowband survey designed to detect emission-line galaxies (ELGs) and quasi-stellar objects (QSOs) over a wide...
  • SFACT. II. SFF01 -10 and -15 emission line objects

    Star Formation Across Cosmic Time (SFACT) is a new narrowband (NB) survey designed to detect faint emission-line galaxies (ELGs) and QSOs over a broad range of redshifts. Here...
  • Chemical abundances for 5 stars in Tucana II

    We present chemical abundances and velocities of five stars between 0.3 and 1.1kpc from the center of the TucanaII ultrafaint dwarf galaxy (UFD) from high-resolution...
  • Euclid ERO Perseus cluster dwarfs

    We make use of the unprecedented depth, spatial resolution, and field of view of the Euclid Early Release Observations (EROs) of the Perseus galaxy cluster to detect and...
  • Deep u'g'r' obs. of galaxies in A262 & A1656

    In this study, we compare the structural parameters of ultradiffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population. We...
  • M2FS & Hectochelle spectra of dSph in the MW halo

    We present spectroscopic data for 16369 stellar targets within and/or toward 38 dwarf spheroidal galaxies and faint star clusters within the Milky Way halo environment. All...
