We report the detection of 1.3mm continuum and near-infrared K−band (2.2μm) emission from the submillimeter galaxy SMMJ00266+1708. Although this galaxy is among the brightest sub-mm sources detected in the blank-sky surveys (L ∼ 10L⊙), SMMJ00266+1708 had no reliable optical/nearinfrared counter-part. We used sensitive interferometric 1.3mm observations with the Owens Valley Millimeter Array to ...
We present results from the Las Campanas Infrared Survey, designed to identify a statistically significant sample of z > ∼ 1 galaxies using photometric redshift techniques. Here we summarize the design and strategies of the survey and present the first estimate of the galaxy luminosity function at z > ∼ 1 based on H-band selected galaxies identified in our survey. Results of number count studie...
We present results of a search for galaxies around the highly obscured giant radio galaxy PKS1343– 601 using the near-infrared DENIS survey. We compare our findings with surveys in the B-band, at the 21 cm line emission, and with 2MASS. Recession velocities of galaxies in this area suggest a low-velocity-dispersion group or cluster of galaxies including an X-ray confirmed Seyfert 2. The colours...
Loch Ness Monsters (Nessies) are–if they exist–animals of a species either not yet known to science or known but thought to have been long extinct. Much controversy has concerned eyewitness testimonies and photographs whose relevance and validity are uncertain. However, there also exists a body of objective evidence that critics have been unable to gainsay: the Dinsdale film; numerous sonar ech...

In dryland regions, increased demand for water has led to the reduction of natural aquatic habitats and threatens persisting aquatic habitats. In the Madrean Sky Islands (MSI), water demands have also resulted in the creation of novel aquatic habitats, including stock ponds. Stock ponds are important surrogate habitat for native species, yet little is known about the aquatic invertebrates utili...
The predictive modeling competition platform Kaggle TM recently posed the Observing Dark Worlds prize, challenging researchers to design a supervised learning algorthim that predicts the position of dark matter halos in images of the night sky. Although dark matter neither emits nor absorbs light, its mass bends the path of a light beam passing near it. Regions with high densities of dark matte...
Careful modelling of the stellar and gaseous distributions in the Milky Way disc has been carried out in order to study the stellar warp. We have analysed the observations in the near infrared made by the ”Diffuse Infrared Background Experiment” (DIRBE) on board COBE as reported by Freudenreich et al. (1994). These authors found a dependence of the displacement of the maximum emission on galact...
I review the development of UV and EUV astronomy, covering the spectral range from 5 to 300 nm, with emphasis on sky surveys for discrete sources. I discuss studies which resulted in lists of sources observed by imaging and deliberately omit most spectroscopic studies. Technical issues, such as detector and telescope developments, are treated separately from descriptions of specific missions an...
