We searched for planetary nebulae (PNe) in the nearby spiral galaxy M33 using the Wide Field Camera at the 2.54 m Isaac Newton Telescope of La Palma (Spain)...
A search for radio counterparts to Chandra ULX candidates
We present a systematic search for radio counterparts to Ultraluminous X-ray (ULX) source candidates based on a cross-correlation of the Swartz et al. (2004)...
A search for spectral features in the XMM-Newton observation of UGC 11763
We have performed the analysis of the X-ray XMM-Newton spectra of the narrow line Seyfert 1 galaxy UGC 11763 (Mkn 1513). We have studied the EPIC data in the...
A Search for Spectral Hysteresis and Energy-dependent Time Lags from X-Ray and TeV Gamma-Ray Observations of Mrk 421
Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars...
A significant hardening and rising shape detected in the MeV/GeV νFν spectrum from the recently discovered very-high-energy blazar S4 0954+65 during the bright optical flare in 2015 February
We report on Fermi Large Area Telescope (LAT) and multi-wavelength results on the recently discovered very-high-energy (VHE, E > 100 GeV) blazar S4 0954+65 (z =...
A simultaneous search for high-z LAEs and LBGs in the SHARDS survey
We have undertaken a comprehensive search for both Lyman alpha emitters (LAEs) and Lyman break galaxies (LBGs) in the Survey for High-z Absorption Red and Dead...
A SINFONI view of circum-nuclear star-forming rings in spiral galaxies
We present near-infrared (H- and K-band) SINFONI integral-field observations of the circumnuclear star formation rings in five nearby spiral galaxies. We made...
A SINFONI View of Galaxy Centers: Morphology and Kinematics of Five Nuclear Star Formation-Rings
We present near-infrared (H- and K-band) integral-field observations of the circumnuclear star formation rings in five nearby spiral galaxies. The data...
A slow bar in the lenticular barred galaxy NGC 4277
Aims: We characterised the properties of the bar hosted in lenticular galaxy NGC 4277, which is located behind the Virgo cluster. Methods: We measured the bar...
