A remarkably large depleted core in the Abell 2029 BCG IC 1101
We report the discovery of an extremely large (Rb ∼2.77 arcsec ≈ 4.2 kpc) core in the brightest cluster galaxy, IC 1101, of the rich galaxy cluster Abell 2029...
A Robust Age Indicator for Old Stellar Populations
We derive new spectral Hγ index definitions that are robust age indicators for old and relatively old stellar populations and therefore have great potential for...
A sample of dust attenuation laws for Dark Energy Survey supernova host galaxies
Context. Type Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections...
Kinematic and population studies show that bulges are generally rotationally flattened systems similar to low-luminosity ellipticals. However, observations with...
A SCUBA-2 selected Herschel-SPIRE dropout and the nature of this population
Dusty star-forming galaxies (DSFGs) detected at z > 4 provide important examples of the first generations of massive galaxies. However, few examples with...
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...
