  • VLT JHKs imaging of RCW 38

    We present the results of high angular resolution adaptive optics (AO) near-infrared (JHKs) observations of the deeply embedded massive cluster RCW 38 using NACO on the Very...
  • 2MASS large-amplitude variable stars

    We present a catalog of variable stars in the near-infrared wavelength detected with overlapping regions of the Two Micron All Sky Survey public images, and discuss their...
  • GLIMPSE Extended Green Objects catalog

    Using images from the Spitzer Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE), we have identified more than 300 extended 4.5um sources (Extended Green Objects...
  • H{alpha} stars and HH objects near BRCs

    We have carried out near-IR/optical observations to examine star formation toward a bright-rimmed cometary globule (BRC37) facing the exciting star(s) of an HII region (IC1396)...
  • X-ray and IR sources in RCW 38

    We report on results of a 96.7ks Chandra observation of one of the youngest, most embedded, and most massive young stellar clusters studied in X-rays: RCW 38. We detect 460...
  • X-ray and NIR studies of L1448

    We present the results of X-ray and near-infrared (NIR) observations of L1448, a star-forming region in the Perseus cloud complex using the Chandra X-Ray Observatory and the 4m...
  • YSO near-infrared properties

    We present high-resolution (R~18000), high signal-to-noise ratio, 2{mu}m spectra of 52 IR-selected Class I and flat-spectrum young stellar objects in the Taurus-Auriga, {rho}...
  • Catalog of source parameters in NICMOS UDF

    This paper describes the observations and data reduction techniques for the version 2.0 images and catalog of the Near-Infrared Camera and Multi-Object Spectrometer Ultra Deep...
  • Faint Chandra sources in SWIRE

    We exploit deep combined observations with Spitzer and Chandra of the Spitzer Wide-Area Infrared Extragalactic Survey (SWIRE) in the ELAIS N1 region to investigate the nature of...
  • Mid-IR photometry in the Orion Nebula

    We present two wide-field (~5'x3.5'), diffraction-limited ({lambda}/D~0.5" at 10{mu}m), broadband 10 and 20{mu}m images of the Orion Nebula, plus six 7-13{mu}m narrowband images...
  • 2MASS counterparts for OH/IR stars

    The positions of the IRAS counterparts to the 420 OH/IR stars in the Arecibo sky (0{deg}<{delta}<+38{deg}) are usually accurate to better than 10". But every star has...
  • MSX 8.3um fluxes of star-forming regions

    We have imaged seven nearby star-forming regions, the Rosette Nebula, the Orion Nebula, W3, the Pleiades, G300.2-16.8, S263, and G159.6-18.5, with the Spatial Infrared Imaging...
  • H{alpha} stars and HH objects near BRCs

    Bright-rimmed clouds (BRCs) found in H II regions are probably sites of triggered star formation due to compression by ionization/shock fronts. Many BRCs harbor IRAS point...
  • K survey of Ori A molecular cloud

    We present results from a 2.2{mu}m (limiting K about 14.5mag) survey of the northern portion of the Orion A molecular cloud. A total of 3548 sources were detected in the...
  • Extragalactic IRAS sources

    Extragalactic sources detected at lambda=60um were selected from the IRAS Faint Source Catalog, Version 2 (Cat. II/156) by the criterion S(60um)>=S(12um). They were...
  • 6.7GHz methanol maser emission survey

    We report the first results of a search for 6.7GHz methanol masers in the direction of 1399 IRAS objects north of declination -20{deg} with the flux densities greater than 100...
  • NIR photometry of IRAS sources. III

    We present the near infrared photometry of a new sample of 225 IRAS sources, many of them previously unidentified in the literature, selected because their far infrared colours...
  • W3 star-forming region 345 GHz survey

    Results are presented of the 345 GHz spectral survey toward three sources in the W 3 Giant Molecular Cloud: W 3 IRS4, W 3 IRS5 and W 3(H_2_O). Nearly 90% of the atmospheric...
  • IR photometry of ESO calibration stars

    We describe the infrared (IR) photometric system for the single channel photometers at ESO, which have been used from 1983 until 1994. In addition to the broadband near infrared...
  • Hickson Compact Groups of Galaxies I.

    The Far Infrared (FIR) properties of galaxies which are members of compact groups bear relevant information on the dynamical status and the physical properties of these...
