  • The Swift/UVOT+MaNGA (SwiM) v4.1 catalog

    We present the the new Swift/UVOT+MaNGA (SwiM) catalog (SwiM_v4.1). SwiM_v4.1 is designed to study star formation and dust attenuation within nearby galaxies given the unique...
  • ISO supernovae remnants spectra

    We present far-infrared (FIR) spectroscopy of supernova remnants (SNRs) based on the archival data of the Infrared Space Observatory taken with the Long Wavelength Spectrometer...
  • SDSS Seyfert 1.9 galaxies with Ha emission line fit

    The traditional classification for a subclass of the Seyfert galaxies is visual inspection or using a quantity defined as a flux ratio between the Balmer line and forbidden...
  • Spectroscopic and transit obs. of WASP-148

    We present spectroscopic measurements of the Rossiter-McLaughlin effect for WASP-148b, the only known hot Jupiter with a nearby warm-Jupiter companion, from the WIYN/NEID and...
  • Optical phot. and sp. monitoring of SN 2020sck

    We present optical UBVRI photometry and low-to-medium resolution spectroscopic observations of type Iax supernova SN 2020sck spanning -5.5 days to +67 days from maximum light in...
  • MgII, FeII & 3000{AA} continuum LCs of CTA102

    We report on the detection of a statistically significant flare-like event in the MgII{lambda}2798{AA} emission line and the UV FeII band of CTA 102 during the outburst of fall...
  • NIR spectra of SN 2014C 1-5yr post-explosion

    Supernova (SN) 2014C is unique: a seemingly typical hydrogen-poor SN that started to interact with a dense, hydrogen-rich circumstellar medium (CSM) ~100 days post-explosion....
  • SALT spectrum of CXOU J005440.5-374320

    We investigate the nature of CXOU J005440.5-374320 (J0054), a peculiar bright (~4x10^39^erg/s) and soft X-ray transient in the spiral galaxy NGC300 with a six-hour periodic flux...
  • U Equ spectra and multi-photometry

    U Equ is an unusual maser-hosting infrared source discovered in the 1990s. It was tentatively classified as a post-asymptotic giant branch (post-AGB) star with a unique optical...
  • Age resolution in stellar population synthesis

    As the reconstruction of the star-formation histories (SFH) of galaxies from spectroscopic data becomes increasingly popular, we explore the best age resolution achievable with...
  • Leveraging HST with MUSE II

    Ancient (>10Gyr) globular clusters (GCs) show chemical abundance variations in the form of patterns among certain elements, e.g. N correlates with Na and anticorrelates with...
  • 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...
  • VLT Spectroscopy of Ultra-faint Dwarf Galaxies. I.

    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...
  • SDSS-IV/MaNGA ; galaxy stellar and HI masses

    Gaseous inflows are necessary suppliers of galaxies star-forming fuel, but are difficult to characterize at the survey scale. We use integral-field spectroscopic measurements of...
  • FeI and FeII abundances with LOTUS

    Precise fundamental atmospheric stellar parameters and abundance determination of individual elements in stars are important for all stellar population studies. Non-local...
  • 115 HARPS-N and ESPRESSO radial velocity for K2-136

    K2-136 is a late-K dwarf (0.742{+/-}0.039M{sun}) in the Hyades open cluster with three known, transiting planets and an age of 650{+/-}70Myr. Analyzing K2 photometry, we found...
  • Star-forming complex S254-S258 HII regions

    The S254-258 star-forming complex is a place of massive star formation where five OB-stars have created HII regions, visible as optical nebulae, and disrupted the parental...
  • CGM2 galaxy-OVI absorber pairs

    We combine 126 new galaxy-OVI absorber pairs from the CGM^2^ survey with 123 pairs drawn from the literature to examine the simultaneous dependence of the column density of OVI...
  • Abundances in 16 red-giant in NGC 7789

    We have gathered optical-region spectra, derived model atmosphere parameters, and computed elemental abundances for 15 red giant stars in the open cluster NGC7789. We focus on...
  • Primordial S-type family catalogue

    We present the results of our study about a newly discovered asteroid family in the inner main belt: the primordial S-type family. From an initial list of 263 asteroids that are...
