ISO Observations of Quasars and Quasar Hosts [PDF]
, 1997 The Infrared Space Observatory (ISO), launched in November 1995, allows us to measure the far-infrared (far-IR) emission of quasars in greater detail and over a wider energy range than previously possible. In this paper, preliminary results in a study of the 5--200 $ m$ continuum of quasars and active galaxies are presented. Comparison of the spectral

Frontiers in Astronomy and Space Sciences, 2017 Prior to the Fermi-LAT era, only two classes of Active Galactic Nuclei (AGN) were thought to harbor relativistic jets that radiate up to gamma-ray energies: blazars and radio galaxies. The detection of variable gamma-ray emission from Narrow Line Seyfert

The Astrophysical Journal, 2023 Massive galaxies formed most actively at redshifts z = 1–3 during the period known as “cosmic noon.” Here we present an emission-line study of the extremely red quasar SDSSJ165202.64+172852.3’s host galaxy at z = 2.94, based on observations with the Near

Chemistry &Biodiversity, EarlyView.ABSTRACT Volatile secondary metabolites in plants can serve as valuable biomarkers for the plant's health, stress response, and pest or disease detection. We have investigated the volatilome of Acer saccharum (sugar maple) leaves using two complementary extraction techniques: headspace‐solid phase micro‐extraction coupled with gas chromatography‐mass ...

Magnetic Resonance in Medicine, EarlyView.Abstract Purpose To develop a novel MR fingerprinting sequence using optimized motion‐compensated diffusion preparations for simultaneous T1, T2, and ADC quantification of liver tissue in a single breath‐held scan. Methods A radial spoiled gradient echo acquisition with magnetization preparation modules for T1, T2, and ADC encoding is proposed.

DPQP: A Detection Pipeline for Quasar Pair Candidates Based on QSO Photometric Images and Spectra
Universe, 2023 Quasars have an important role in the studies of galaxy evolution and star formation. The rare close projection of two quasars in the sky allows us to study the environment and matter exchange around the foreground quasar (QSOfg) and the background ...

Journal of the American Ceramic Society, EarlyView.Development of cordierite lattice structures from DIW of silicone‐based emulsions, in multiple forms (aqueous phase as suspension of oxide nanoparticles, as solution of Mg and Al salts, or as solution/suspension). Abstract The development of advanced ceramic materials with tailored microstructures is essential for meeting the demands of many high ...

The Jets in Micro-Quasars and Quasars: A Comparison [PDF]
Highlights of Astronomy, 2005 AbstractThe discovery of relativistic jets in radio emitting X-ray binaries in our own galaxy has led to the term ‘microquasar’ being coined for these objects. In this paper the properties of microquasars are compared with those of quasars and radio galaxies, with the aim of trying to see how the similarities and differences can inform us about the ...
