PKS 1718-649 is one of the closest and most comprehensively studied candidates of a young active galactic nucleus (AGN) that is still embedded in its optical...
Extragalactic globular cluster near-infrared spectroscopy: I. Integrated near-infrared spectra of Centaurus A/NGC 5128
Context. One way to constrain the evolutionary histories of galaxies is to analyse their stellar populations. In the local Universe, our understanding of the...
Extragalactic globular cluster near-infrared spectroscopy: II. The stellar population synthesis model zero-point problem extends to the near-infrared
Many recent studies have pointed out significant discrepancies between observations and models of stellar populations in the near-infrared (NIR). With current...
Extrasolar planet detection by binary stellar eclipse timing: evidence for a third body around CM Draconis
Aims:Our objective is to elucidate the physical process that causes the observed observed-minus-calculated (O-C) behavior in the M4.5/M4.5 binary CM Dra and to...
Extreme emission-line galaxies out to z ~ 1 in zCOSMOS. I. Sample and characterization of global properties
Context. The study of large and representative samples of low-metallicity star-forming galaxies at different cosmic epochs is of great interest to the detailed...
Aims: We aim to characterize the multiwavelength emission from Markarian 501 (Mrk 501), quantify the energy-dependent variability, study the potential multiband...
Aims:We investigate the statistical properties of the extreme events of the solar cycle as measured by the sunspot number. Methods: The recent advances in the...
Extreme-ultraviolet (EUV) observables of simulated plasmoid-mediated reconnection in the solar corona
Context. Understanding the role of magnetic reconnection in the heating and dynamics of the solar atmosphere requires detailed observational data of any...
