  • New VVV Survey Globular Cluster Candidates in the Milky Way Bulge 

    Minniti, Dante; Geisler, Douglas; Alonso-García, Javier; Palma, Tali; Beamin, Juan Carlos; Borissova, Jura; Catelan, Marcio; Clariá, Juan J.; Cohen, Roger E.; Ramos, Rodrigo Contreras; Dias, Bruno; Fernandez-Trincado, Jose; Gomez, Matias; Hempel, Maren; Ivanov, Valentin D.; Kurtev, Radostin; Lucas, Philip; Moni-Bidin, Christian; Pullen, Joyce; Alegría, Sebastian Ramírez; Saito, Roberto K.; Valenti, Elena (2017-11-10)
    It is likely that a number of Galactic globular clusters remain to be discovered, especially toward the Galactic bulge. High stellar density combined with high and differential interstellar reddening are the two major ...
  • The HP2 Survey - IV. The Pipe nebula : Effective dust temperatures in dense cores 

    Hasenberger, Birgit; Lombardi, Marco; Alves, João; Forbrich, Jan; Hacar, Alvaro; Lada, Charles J. (2018-07-16)
    Multi-wavelength observations in the sub-mm regime provide information on the distribution of both the dust column density and the effective dust temperature in molecular clouds. In this study, we created high-resolution ...
  • Radiative age mapping of the remnant radio galaxy B2 0924+30 : The LOFAR perspective 

    Shulevski, A.; Morganti, R.; Harwood, J. J.; Barthel, P. D.; Jamrozy, M.; Brienza, M.; Brunetti, G.; Röttgering, H. J.A.; Murgia, M.; White, G. J.; Croston, J. H.; Brüggen, M. (2017-04-01)
    We have observed the steep spectrum radio source B2 0924+30 using the LOw Frequency ARray (LOFAR) telescope. Hosted by a z = 0.026 elliptical galaxy, it has a relatively large angular size of 12′ (corresponding to 360 kpc ...
  • Squeezed between shells? On the origin of the Lupus I molecular cloud. - II. APEX CO and GASS HI observations 

    Gaczkowski, B.; Roccatagliata, V.; Flaischlen, S.; Kroell, D.; Krause, M.~G.~H.; Burkert, A.; Diehl, R.; Fierlinger, K.; Ngoumou, J.; Preibisch, T. (2017-12-12)
    Context. The Lupus I cloud is found between the Upper-Scorpius (USco) and the Upper-Centaurus-Lupus (UCL) sub-groups of the Scorpius-Centaurus OB-association, where the expanding USco H I shell appears to interact with a ...
  • In-depth study of moderately young but extremely red, very dusty substellar companion HD206893B 

    Delorme, P.; Schmidt, T.; Bonnefoy, M.; Desidera, S.; Ginski, C.; Charnay, B.; Lazzoni, C.; Christiaens, V.; Messina, S.; D'Orazi, V.; Milli, J.; Schlieder, Joshua E.; Gratton, R.G.; Rodet, L.; Lagrange, A-M; Absil, O.; Vigan, A.; Galicher, R.; Hagelberg, J.; Bonavita, Mariangela; Lavie, B.; Zurlo, A; Olofsson, J.; Boccaletti, A.; Cantalloube, F.; Mouillet, D.; Chauvin, G.; Hambsch, F. -J.; Langlois, M.; Udry, S.; Henning, Th; Beuzit, J-L; Mordasini, Christoph; Lucas, P.; Marocco, F.; Biller, B.; Carson, J.; Cheetham, A.; Covino, E.; Caprio, V. De; Delboulbe, A.; Feld, M.; Girard, J.H.V.; Hubin, N.; Maire, A-L; Pavlov, A.; Petit, C.; Rouan, D.; Roelfsema, R.; Wildi, F. (2017-12-08)
    The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties of the companion, which has the reddest ...
