We use 3,213 Active Galactic Nuclei (AGNs) from the $\it{XMM}$-XXL northern field to investigate relation of AGN type with host galaxy properties. Applying a Bayesian method, we derive hardness ratios (HRs) and through these hydrogen column density ($\rm N_H$) for each source. consider as absorbed sources (type-2) those $\rm N_H > 10^{21.5}\, \rm{cm^{-2}}$. examine star formation rate (SFR) wel...

We investigate the connection between galactic outflows and star formation using two independent data sets covering a sample of 22 galaxies 1 ? z 1.5. The Hubble Space Telescope WFC3/G141 grism provides low spectral resolution, high spatial resolution spectroscopy yielding H? emission-line maps from which we measure extent strength formation. In rest-frame near-UV, Keck/DEIMOS observes Fe ii Mg...

We present a study of the relationship between black hole accretion rate (BHAR) and star formation (SFR) in sample giant elliptical galaxies. These galaxies, which live at centers galaxy groups clusters, have activity that is primarily fueled by gas condensing out hot intracluster medium. For 46 galaxies spanning 5 orders magnitude BHAR SFR, we find mean ratio log(BHAR/SFR) = -1.45 +/- 0.2, ind...

Using Hα spectra of 114 rest-frame UV-selected galaxies at z ∼ 2, we compare inferred star formation rates (SFRs) with those determined from the UV continuum luminosity. After correcting for extinction using standard techniques based on the UV continuum slope, we find excellent agreement between the indicators, with 〈SFRHα〉 = 31 M⊙ yr −1 and 〈SFRUV〉 = 29 M⊙ yr . The agreement between the indica...

The stretch of the cardiac muscle is immediately followed by an increase in the contraction strength after which occurs a slow force increase (SFR) that takes several minutes to fully develop. The SFR was detected in a wide variety of experimental preparations including isolated myocytes, papillary muscles and/or trabeculae, left ventricle strips of failing human myocardium, in vitro isovolumic...

Objectives: To compare outcome of open ureterolithotomy versus semi-rigid ureteroscopy in management of large upper ureteric stones. Patients and Methods: Patients with large upper ureteric stones (≥2cm) who were managed by ureteroscopy (31 patients) or ureterolithotomy (31 patients) were included retrospectively from January 2012 to December 2014. Primary stone-free rate (SFR), secondary SFR (...

We use a large-scale ΛCDM hydrodynamical simulation to assess the dependence of the cosmic Star Formation Rate (SFR) on overdensity of luminosity.

We investigate the impact of spiral structure on global star formation using a sample 2226 nearby bright disk galaxies. Examining relationship between arms, rate (SFR), and stellar mass, we find that arm strength correlates well with variation SFR as function mass. Arms are stronger above star-forming galaxy main sequence (MS) weaker below it: increases higher $\log\,({\rm SFR}/{\rm SFR}_{\rm M...

BACKGROUND Circadian ( approximately 24 hr) rhythms are generated by the central pacemaker localized to the suprachiasmatic nucleus (SCN) of the hypothalamus. Although the basis for intrinsic rhythmicity is generally understood to rely on transcription factors encoded by "clock genes", less is known about the daily regulation of SCN neuronal activity patterns that communicate a circadian time s...
