An Anomaly in the Angular Distribution of Quasar Magnitudes: Evidence for a Bubble Universe with a Mass ~10^21 M\odot
Anomaly Angular Distribution Quasar Magnitudes Bubble Universe Mass
2012/2/21
Quasars provide our farthest-reaching view of the Universe. The Sloan Survey now contains over 100,000 quasar candidates. A careful look at the angular distribution of quasar magnitudes shows a surpri...
Environmental Effects on the Metal Enrichment of Low Mass Galaxies in Nearby Clusters
Environmental Effects the Metal Enrichment Low Mass Galaxies Nearby Clusters
2012/2/21
In this paper we study the chemical history of low-mass star-forming (SF) galaxies in the local Universe clusters Coma, A1367, A779, and A634. The aim of this work is to search for the imprint of the ...
Merger induced scatter and bias in the cluster mass - Sunyaev-Zeldovich effect scaling relation
cosmology: large-scale structure of Universe, galaxies: clusters: general, meth- ods: N-body simulations
2011/10/20
We examine sources of scatter in scaling relations between galaxy cluster mass and thermal Sunyaev-Zeldovich (SZ) effect using cluster samples extracted from cosmological hydrodynamical simulations. O...
The intrinsic dispersion of the Faber-Jackson relation for early-type galaxies as function of the mass and redshift
Galaxies fundamental parameters photometry distances redshifts
2011/10/18
Aims. Recently it has been reported that the intrinsic dispersion at constant magnitude of the structural relations from early-type galaxies is a useful tool to study the universality of these structu...
The mass function of black holes at 1
mass function black holes comparison models observations
2011/10/19
In this paper, we compare the observationally derived black hole mass function (BHMF) of luminous broad-line quasars (BLQSOs) at 1SS) presented in Kel...
Using HST observations of 147 host galaxies of low-mass black holes (BHs), we systematically study the structures and scaling relations of these active galaxies. Our sample is selected to have central...
Black Hole Mass and Bulge Luminosity for Low-mass Black Holes
Black Hole Mass Bulge Luminosity Low-mass Black Holes
2011/10/12
We study the scaling between bulge magnitude and central black hole (BH) mass in galaxies with virial BH masses < 10^6 solar mass. Based on careful image decomposition of a snapshot Hubble Space Teles...
BLR Physical Conditions in Extreme Population A Quasars: a Method to Estimate Central Black Hole Mass at High Redshift
Physical Conditions Extreme Population Quasars
2011/10/10
We describe a method for determination of physical conditions in the broad line regions of a significant subsample of Seyfert-1 nuclei and quasars. Several diagnostic ratios based on intermediate (AlI...
Subaru weak-lensing study of A2163: bimodal mass structure
Subaru weak-lensing bimodal structure
2011/9/26
We present a weak-lensing analysis of the merging cluster A2163 using Subaru/Suprime-Cam and CFHT/Mega-Cam data and discuss the dynamics of this cluster merger, based on complementary weak-lensing, X-...
The Effect of Screening Factors and Thermonuclear Reaction Rates in the Pre-main Sequence Evolution of Low Mass Stars
Low mass stars thermonuclear reaction rates electron screening factors composition changes
2010/9/15
In understanding the nucleosynthesis of the elements in stars,one of the most important quantities is the reaction rate and it must be evaluated in terms of the stellar temperature T , and its determi...
