ABSTRACT In this work, we present the results of a detailed X-ray spectral analysis brightest active galactic nuclei (AGNs) detected in XMM–Newton 1.75 Ms Ultra Narrow Deep Field. We analysed 23 AGNs that have luminosity range $\sim 10^{42} {\!-\!} 10^{46}\, \rm {erg}\, {s}^{-1}$ $2 10\, {keV}$ energy band, redshifts up to 2.66, and 10\,000$ photon counts $0.3{ \!-\! }10\, band.

Methods.We applied distinct selection criteria to attain an SFG sample with minimal AGN contamination. Multiple approaches were used estimate the intrinsic extinction, SFR and gas-phase metallicity for SFGs. In conjunction findings in literature, we examined correlation between SFRs stellar masses ($M_*$), as well evolution depending on $M_*$. Finally, 3D relationship $M_*$, metallicity, is also studied.} Results. From initial spectroscopic of 409 FIR-selected objects from Lockman--SpReSO...
Aims. In this work, we carry out a comprehensive study using galaxy data from the Lockman Spectroscopic Redshift Survey Osiris (Lockman-SpReSO) project, far-infrared (FIR) selected sample of galaxies observed optical spectroscopy. We analyse sub-sample star-forming (SFGs) with secure spectroscopic redshifts, mostly in luminous infrared (IR) domain. From these galaxies, parameters such as extinction, star formation rate (SFR), and metallicity have been derived. The present paper examines how...
Abstract In this work, we present the results of survey carried out on one deepest X-ray fields observed by XMM-Newton satellite. The 1.75 Ms Ultra Narrow Deep Field (XMM175UNDF) is made 13 observations taken over 2 yr with a total exposure time (1.372 after flare-filtered) in field 30′ × centered around blazar 1ES 1553+113. We stacked reaching flux limits 4.03 10 −16 , 1.3 −15 and 9.8 erg s −1 cm −2 soft (0.2–2 keV), hard (2–12 full (0.2–12 keV) bands, respectively. Using conservative...
In this work we estimate the Star Formation Rate (SFR) through 333 Long-GRBs detected by Swift. This investigation is based on empirical model proposed Y\"uksel et al. (2008), basically, SFR estimated using long-GRBs considering that they have an stellar origin Collapsar or collapse of massive stars (Hypernova) $M>20 M_{\bigodot} $. The analysis starts with study $\varepsilon (z)$ which accounts production rate and it parameterized $\varepsilon(z)=\varepsilon_{0}(1+z)^{\delta} $ where...
We present a detailed analysis of XMM-Newton X-ray spectra the Narrow-Line Seyfert 1 galaxy Mrk 1044. find robust evidence for multi-phase, ultra-fast outflow, traced by four separate components in grating spectrum. One component has high column density and ionization state, is outflowing at 0.15c. The other three wind have lower temperature, density, outflow velocities 0.08c. This structure strikingly similar to that found IRAS 17020+4544, suggesting stratified winds may be common feature...
