  • Pristine Inner Galaxy Survey PIGS VIII

    The oldest stars in the Milky Way (born in the first few billion years) are expected to have a high density in the inner few kpc, spatially overlapping with the Galactic bulge....
  • Mira variable cand. in Milky Way NSD region

    A key event in the history of the Milky Way is the formation of the bar. This event affects the subsequent structural and dynamical evolution of the entire Galaxy. When the bar...
  • ART-XC Galactic bulge survey point sources cat.

    We present a catalog of point sources detected with the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory during a wide-field survey of the Galactic Bulge that was...
  • Abundance catalogue of solar twins in GALAH

    Stellar chemical abundances have proved themselves a key source of information for understanding the evolution of the Milky Way, and the scale of major stellar surveys such as...
  • PN chemical abundances in Galactic Bulge

    In this, the third of a series of papers, we present well determined chemical abundances for 124 Planetary nebulae (PNe) in the Galactic bulge from deep, long-slit FORS2 spectra...
  • Galactic distribution of pulsar scattering

    Interstellar radio-wave scattering leads to flux density fluctuations and pulse broadening of pulsar signals. However, Galactic distribution and the structure of the scattering...
  • Reduced proper motion with Gaia DR3

    With the advent of the European Space Agency's Gaia mission and its recent data releases EDR3 and DR3, the astronomy community has obtained the largest-ever cartograph of our...
  • Stellar Populations of NSC and NSD

    The Milky Way nuclear star cluster (NSC) is located within the nuclear stellar disc (NSD) in the Galactic Centre. It is not fully understood if the formation and evolution of...
  • Accreted halo stars abundances

    Understanding the assembly of our Galaxy requires us to also characterize the systems that helped build it. In this work, we accomplish this by exploring the chemistry of...
  • Collision of two stellar associations

    Based on Gaia DR2 data and new CHIRON radial velocities, we have discovered that two nearby stellar associations UPK 535 (318.08+/-0.29pc, 25^+15^-10_Myr, 174 stars) and Yep 3...
  • ATOMS IV Gas clumps properties and SFRs

    We report the detection of radio recombination line (RRL) H_40{alpha} towards 75 sources, with data obtained from ACA (Atacama Compact 7 m Array) observations in the ATOMS (ALMA...
  • Microlensing events in VVV light curves

    The VISTA Variables in the Via Lactea (VVV) survey and its extension have been monitoring about 560 deg^2^ of sky centred on the Galactic bulge and inner disc for nearly a...
  • SCORPIO field's study with ASKAP

    In the broad context of the Australian Square Kilometer Array Pathfinder (ASKAP) early-science phase and preparation for the related surveys, we report the first radio...
  • The GALAH+ Survey DR3

    The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution of...
  • Gaia EDR3 view on Galactic globular clusters

    We use the data from Gaia Early Data Release 3 (EDR3) to study the kinematic properties of Milky Way globular clusters. We measure the mean parallaxes and proper motions (PM)...
  • The extended MILES library

    Extragalactic astronomy and stellar astrophysics are intrinsically related. In fact, the determination of important galaxy properties such as stellar masses, star formation...
  • Tidal tails in the open cluster NGC 752

    We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5...
  • Study of Cepheids in open clusters

    In this paper, we revisit the problem of identifying bona fide cluster Cepheids by performing an all-sky search for Cepheids associated with open clusters and making use of...
  • Gaia/IPHAS catalogue of Ha-excess sources

    We present a catalogue of point-like H{alpha}-excess sources in the Northern Galactic Plane. Our catalogue is created using a new technique that leverages astrometric and...
  • Short-period binaries in the inner VVV bulge

    Most of our knowledge of the structure of the Milky Way has come from the study of variable stars. Among these variables, mimicking the periodic variation of pulsating stars,...
