The mean star formation rate of X-ray selected active galaxies and its evolution from z~2.5: results from PEP-Herschel [PDF]
, 2012 We study relationships between star-formation rate (SFR) and the accretion luminosity and nuclear obscuration of X-ray selected active galactic nuclei (AGNs) using a combination of deep far-infrared (FIR) and X-ray data in three key extragalactic survey ...

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa
Advanced Science, EarlyView.Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

RECALIBRATION OF THE VIRIAL FACTOR AND MBH–σ* RELATION FOR LOCAL ACTIVE GALAXIES [PDF]
, 2012 Determining the virial factor of the broad-line region gas is crucial for calibrating active galactic nucleus black hole mass estimators, since the measured line-of-sight velocity needs to be converted into the intrinsic virial velocity.

The Astrophysical JournalAccretion supermassive black holes in the center of active galaxies usually produce “jet”-collimated bipolar outflows of relativistic particles. Magnetic fields near the black hole event horizon may play a crucial role in the formation of jets/outflows ...

Gas flows in galactic nuclei: observational constraints on BH-galaxy coevolution [PDF]
, 2016 Galaxy nuclei are a unique laboratory to study gas flows. High-resolution imaging of the gas flows in galactic nuclei are instrumental in the study of the fueling and the feedback of star formation and nuclear activity in nearby galaxies. Several fueling mechanisms can be now confronted in detail with observations done with state-of-the-art ...

Field galaxies and their AGNs: Nature versus nurture [PDF]
Serbian Astronomical Journal, 2013 This review attempts to present most recent findings related to the very controversial question of which processes guide the flow of gas to the galactic centers where the accretion and growth of supermassive black holes occurs. Also, we put this

The Rise and Fall of Galaxy Activity in Dark Matter Haloes [PDF]
, 2008 We use a SDSS galaxy group catalogue to study the dependence of galaxy activity on stellar mass, halo mass, and group hierarchy (centrals vs. satellites). We split our galaxy sample in star-forming galaxies, galaxies with optical AGN activity and radio sources.
