XDR Chemistry in the Circumnuclear Disk of NGC 1068
(Astronomical Society of the Pacific, 2004)We have studied the feedback in°uence that the central engine of the Seyfert 2 galaxy NGC 1068 may have on the chemistry of the 200 pc circumnuclear gas disk (CND). With this purpose, we have conducted a multispecies/ ... -
xDSL Network Upgrade Employing FPGAs
(Institute of Electrical and Electronics Engineers (IEEE), 2008)This paper proposes an upgrade scenario for xDSL networks to provide broadband access for extendedlink lengths while demonstrating network grooming bymeans of more than one subscriber using a single network connection ... -
The XMM-Newton and Spitzer View of Galaxy/AGN Formation at z = 2-3
(European Space Agency (ESA), 2006-01-01)The genesis of spheroids is central to our understanding of galaxy formation. They contain half of the stellar mass of the Universe, and almost all of the black hole mass. According to galaxy formation models, cluster ... -
XMM-Newton Observations of the Nuclei of the Radio Galaxies 3C 305, DA 240, and 4C 73.08
(2008)We present new XMM-Newton EPIC observations of the nuclei of the nearby radio galaxies 3C 305, DA 240, and 4C 73.08, and investigate the origin of their nuclear X-ray emission. The nuclei of the three sources appear to ... -
XMM-Newton Observations of Three High Redshift Radio Galaxies
(2004)We present results on the physical states of three highredshift powerful radio galaxies (3C292 atz = 0.7, 3C184 at z= 1, and 3C322 atz = 1.7). They were obtained by combining radio measurements with X-ray measurements from ... -
XUE: Molecular Inventory in the Inner Region of an Extremely Irradiated Protoplanetary Disk
(2023-12-01)We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, which focuses on the characterization of planet-forming disks in massive star-forming regions. These regions are ... -
The XXL Survey: : XXIX. GMRT 610 MHz continuum observations
(2018-12-01)We present the 25 square-degree GMRT-XXL-N 610 MHz radio continuum survey, conducted at 50 cm wavelength with the Giant Metrewave Radio Telescope (GMRT) towards the XXL Northern field (XXL-N). We combined previously published ... -
The X–shooter/ALMA Sample of Quasars in the Epoch of Reionization. II. Black Hole Masses, Eddington Ratios, and the Formation of the First Quasars
(2022-12-20)We present measurements of black hole masses and Eddington ratios (λ Edd) for a sample of 38 bright (M 1450 < −24.4 mag) quasars at 5.8 ≲ z ≲ 7.5, derived from Very Large Telescope/X-shooter near-IR spectroscopy of their ... -
Yangian Symmetry for the Tree Amplituhedron
(2017-06-29)Tree-level scattering amplitudes in planar N=4 super Yang-Mills are known to be Yangian-invariant. It has been shown that integrability allows to obtain a general, explicit method to find such invariants. The uplifting of ... -
Yaratıcı Düşüncenin Kişisel Satış Üzerine Etkisi: Perakende Giyim Sektöründe Bir Uygulama
(2017-06-21)The aim of this study is to investigate the impact of the creative strategy on sales performance in the personal selling process in the retail clothing sector. The research model is the descriptive survey model. The ... -
The Yasso07 soil carbon model - Testing against repeated soil carbon inventory
(2012-12-15)Forest soils store large amounts of carbon (C), and releases of C from this pool may significantly increase the CO 2 concentration in the atmosphere. Organic matter decomposition in soils has been shown to strongly depend ... -
