  • BEINGMgII. III. Cool gas reservoirs

    We investigate the origin of intervening cool MgII absorption detected in the spectra of background quasars and the nature of associated galaxies across a broad redshift range...
  • CAVITY spatially resol. SFR of galaxies in voids

    The mass in the Universe is distributed non-uniformly, originating the Large Scale Structure (LSS), characterised by clusters, filaments, walls and voids. Galaxies in voids have...
  • 3C 84 multifrequency radio hybrid images

    Due to its brightness and proximity, the radio galaxy 3C 84 (optical counterpart: NGC 1275 in the Perseus cluster) has been the target for extensive studies to investigate the...
  • Massive stars in nearby galaxies

    Mass loss is a key aspect of stellar evolution, particularly in evolved massive stars, yet episodic mass loss remains poorly understood. To investigate this, we need evolved...
  • CHEPS cold Jupiters RV curves

    The population of long-period giant planets shapes planetary system architectures and formation pathways, but these `cold-Jupiters' remain relatively unexplored. Radial velocity...
  • Transition from outside-in to inside-out at z~2

    By combining high-resolution observations from JWST and HST, we have measured the stellar masses, star formation rates (SFRs), and multi- wavelength morphologies of galaxies in...
  • The Globular cluster Glimpse-C02

    In this paper, we present the results of a detailed photometric analysis of Glimpse-C02, one of the most extincted globular clusters of the Milky Way. We built a deep color...
  • The orbit of S2 star around Sgr A*

    Two recent papers (Ghez et al. 2008ApJ...689.1044G; Gillessen et al. 2009ApJ...692.1075G) have estimated the mass of and the distance to the massive black hole (MBH) in the...
  • IR properties of E and S0 galaxies

    We describe the infrared properties of a large sample of early-type galaxies, comparing data from the Spitzer archive with Ks-band emission from the Two Micron All Sky Survey....
  • Variation of mid-IR extinction

    Based on the data obtained from the Spitzer/Galactic Legacy Infrared Midplane Survey Extraordinaire (GLIPMSE) Legacy Program and the Two Micron All Sky Survey (2MASS) project,...
  • VLA observation of molecular clumps

    We have conducted a search for ionized gas at 3.6cm, using the Very Large Array, toward 31 Galactic intermediate- and high-mass clumps detected in previous millimeter continuum...
  • BLAST Vela sources

    We present first results from an unbiased 50deg^2^ submillimeter Galactic survey at 250, 350, and 500um from the 2006 flight of the Balloon-borne Large Aperture Submillimeter...
  • Local hosts of SNe Ia

    We use multi-wavelength, matched aperture, integrated photometry from the Galaxy Evolution Explorer (GALEX), the Sloan Digital Sky Survey, and the RC3 to estimate the physical...
  • HST view of YSOs in the LMC

    We have used archival Hubble Space Telecope (HST) H{alpha} images to study the immediate environments of massive and intermediate-mass young stellar object (YSO) candidates in...
  • HST F160W photometry in RMC 136

    We present deep Hubble Space Telescope NICMOS 2 F160W band observations of the central 56"x57" (14pcx14.25pc) region around R136 in the starburst cluster 30 Dor (NGC 2070)...
  • LABOCA ECDFS Submillimeter Survey (LESS)

    We present a sensitive 870um survey of the Extended Chandra Deep Field South (ECDFS) combining 310hr of observing time with the Large Apex BOlometer Camera (LABOCA) on the APEX...
  • Faraday rotation in Cen A

    We present the results of an Australia Telescope Compact Array 1.4GHz spectropolarimetric aperture synthesis survey of 34deg^2^ centered on Centaurus A-NGC 5128. A catalog of...
  • The Fermi LAT sky as seen by INTEGRAL/IBIS

    In this Letter we present the result of the cross correlation between the fourth INTEGRAL/IBIS soft gamma-ray catalog, in the range 20-100keV, and the Fermi LAT bright source...
  • X-ray emitters in the Groth-Westphal strip

    The Groth field is one of the sky regions that will be targeted by the OSIRIS Tunable Filter Emission Line Object survey in the optical 820nm and 920nm atmospheric windows. In...
  • LAEs at z~4.5 in the LALA Cetus field

    We present a large sample of Ly{alpha}-emitting galaxies (LAEs) spectroscopically confirmed at redshift z~4.5, based on Inamori-Magellan Areal Camera and Spectrograph...
