We present a compilation of Hubble Space Telescope (HST) images of 58 luminous Sloan Digital Sky Survey (SDSS) type 2 active galactic nuclei (AGNs) at ?. Of these, 42 are type 2 quasars, which is a good representation of all optically selected SDSS type 2 quasars in this z range. We find that the majority of the host galaxies are ellipticals (30/42

We present IACTalks, a free and open access seminars archive (http://iactalks.iac.es) aimed at promoting astronomy and the exchange of ideas by providing high-quality scientific seminars to the astronomical community. The archive of seminars and talks given at the Instituto de Astrofi\'isica de Canarias goes back to 2008. Over 360 talks and

The spectra of the ν_1, ν_2 and 2ν_2 bands were obtained with a quasi-cw stimulated Raman spectrometer. In this technique, two laser beams are focused simultaneously on the sample and their frequency difference scanned, normally by scanning one of them. When this difference matches a Raman transition of the molecule under study, an energy transfer

Aims: The Spectral and Photometric Imaging REceiver (SPIRE) onboard the Herschel space telescope has provided confusion limited maps of deep fields at 250 μm, 350 μm, and 500 μm, as part of the Herschel Multi-tiered Extragalactic Survey (HerMES). Unfortunately, due to confusion, only a small fraction of the cosmic infrared background (CIB) can be

Recently, the discoveries of several nova candidates in M31 have been reported (ATEL #3735, #3976, and #3987), but there have been no spectroscopic confirmations. To classify these objects, we obtained narrow-band H-alpha, Sloan r', and Sloan i'-band CCD images of the central region of M31 using the 2.5-m Isaac Newton Telescope (INT) + WFC at La
