PSR B1951+32 is a gamma -ray pulsar detected by the Energetic Gamma Ray Experiment Telescope (EGRET) and identified with the 39.5 ms radio pulsar in the...
Very high energy observations of the Seyfert galaxy NGC 4151 with MAGIC: Indication of another gamma-ray obscured candidate neutrino source
Seyfert galaxies are emerging as a promising source class of high-energy neutrinos. The Seyfert galaxies NGC 4151 and NGC 1068 have respectively come up as the...
Very High Energy γ-Rays from the Universe's Middle Age: Detection of the z = 0.940 Blazar PKS 1441+25 with MAGIC
The flat-spectrum radio quasar PKS 1441+25 at a redshift of z = 0.940 is detected between 40 and 250 GeV with a significance of 25.5σ using the MAGIC telescopes...
Very high redshift quasars and the rapid emergence of supermassive black holes
The observation of quasars at very high redshift such as Pōniuā'ena is a challenge for models of supermassive black hole (SMBH) formation. This work presents a...
Very high velocity gas in giant extragalactic H II regions.
As part of a systematic survey for the search of high velocity gas in giant extragalactic H II regions, the authors have observed the five largest and brightest...
Very high-energy γ-ray observations of novae and dwarf novae with the MAGIC telescopes
Context. In the last five years the Fermi Large Area Telescope (LAT) instrument detected GeV γ-ray emission from five novae. The GeV emission can be interpreted...
Very Large Telescope Echelle Spectrophotometry of the Planetary Nebula NGC 5307 and Temperature Variations
Echelle spectrophotometry of the planetary nebula NGC 5307 is presented. The data consist of Very Large Telescope Ultraviolet Visual Echelle Spectrograph...
Very Large Telescope-ISAAC Near-Infrared Spectroscopy of ISO-selected Hubble Deep Field South Galaxies
We report the results of near-infrared Very Large Telescope (VLT)-Infrared Spectrometer and Array Camera (ISAAC) spectroscopy of a sample of 12 galaxies at z=0...
