Swift detection of all previously undetected blazars in a micro-wave flux-limited sample of WMAP foreground sources [PDF]
, 2007 Almost the totality of the bright foreground sources in the WMAP CMB maps are blazars, a class of sources that show usually also X-ray emission. However, 23 objects in a flux-limited sample of 140 blazars of the WMAP catalog (first year) were never ...

Review of Education, Volume 10, Issue 1, April 2022., 2022 Abstract Research‐practice partnerships (RPPs) have drawn a great deal of attention as promising structures for bringing educational research and practice closer together. However, promising as RPPs may be, challenges still exist and there have been calls for studies investigating how research can be used within RPPs, and how to include practitioners ...

Directional Association of TeV to PeV Astrophysical Neutrinos with Radio Blazars
, 2020 Recently we have shown that high-energy neutrinos above 200 TeV detected by IceCube are produced within several parsecs in the central regions of radio-bright blazars, that is active galactic nuclei with jets pointing toward us.

Multiwavelength study of high-redshift blazars [PDF]
Monthly notices of the Royal Astronomical Society, 2020 High-redshift blazars are among the most powerful objects in the Universe. The spectral and temporal properties of 33 distant blazars (z > 2.5) detected in the high-energy γ-ray band are investigated by analysing the Fermi-LAT and Swift Ultraviolet and

[Retracted] Current Status of Malignant Tumors after Organ Transplantation
BioMed Research International, Volume 2022, Issue 1, 2022., 2022 Objective. To analyze the diagnosis and treatment of patients with concomitant malignant tumors after organ transplantation by compiling data from organ transplantation patients. Methods. By searching CNKI and PubMed databases, we made a systematic analysis of the studies of postorgan transplantation complicating malignant tumors in the last decade ...

X-ray Spectral Evolution of High Energy Peaked Blazars
Galaxies, 2020 The synchrotron hump of the high energy peaked blazars generally lies in the 0.1–10 keV range and such sources show extreme flux and spectral variability in X-ray bands. Various spectral studies showed that the X-ray spectra of high energy peaked blazars

The Nature of γ-Ray Variability in Blazars [PDF]
Astrophysical Journal, 2019 We present an in-depth and systematic variability study of a sample of 20 powerful blazars, including 12 BL Lacs and 8 flat-spectrum radio quasars, applying various analysis tools such as flux distribution, symmetry analysis, and time-series analysis on ...
