We present the IRAM-30 m observations of multiple-J CO (Jup mostly from 3 up to 8) and [C I](3P2 → 3P1) ([C I](2-1) hereafter) line emission in a sample of redshift 2-4 submillimeter galaxies (SMGs). These SMGs are selected among the brightest-lensed galaxies discovered in the Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS). Forty

Monitoring of 3C 66A during an extended outburst. I. The light curves.
We present results from a two year intensive monitoring of BL Lac object 3C 66A (PKS 0219+428). This object was observed in outburst during these two years. It reached the brightest ever observed magnitude on V=13.59 (1.2.1995) and on K=10.59 (15.2.1994). The optical and infrared light curves are characterised by randomly distributed fast flares

More Evidence for a Population of Intracluster Planetary Nebulae in the Virgo Cluster
We surveyed a 50 arcmin 2 region in the Virgo cluster core to search for intergalactic planetary nebulae and found 11 candidates in the surveyed area. The measured fluxes of these unresolved sources are consistent with these objects being planetary nebulae from an intergalactic population of stars, although we cannot exclude some minor

More Optical Spectroscopy of the X-ray Nova J0422+32
We present the most recent results from our optical spectroscopy campaign on the X-ray Nova/Black Hole Candidate GRO J0422+32. Spectroscopy from the MMT during September 1994, when the system was at R=21 shows that the equivalent width of the H-alpha emission line is 150 Angstroms. Earlier Spectroscopy from March 1994, when the system was at R=20

Morphological studies of SWIRE galaxies in the UGC10214 ACS field
We present the results of a morphological analysis of a small subset of the SWIRE galaxy population. Our analysis is based on public ACS data taken inside the SWIRE N1 field. We distinguish two very general classes of galaxies, bulge- and disc-dominated galaxies, the first class being referred to with the general term 'spheroids' and the second

Morphology and Evolution of the Spiral Jets Observed in the Inner Coma of Comet Hale-Bopp (1995 O1): the 1995 Teide Observing Campaign
CCD monitoring of Comet Hale-Bopp (1995 O1) has been carried out on more than 50 nights using the 82cm IAC-80 Telescope at Teide Observatory (Tenerife, Spain), operated by the Instituto de Astrofísica de Canarias. A combination of deep exposures of the extended coma in BVRI (up to 2 hours total exposure in a single filter) and near nucleus imaging
