Intermediate-mass-ratio-inspirals in the Einstein Telescope. II. Parameter estimation errors
Intermediate-mass-ratio-inspirals Einstein Telescope Parameter estimation errors
2010/11/16
We explore the precision with which the Einstein Telescope (ET) will be able to measure the
parameters of intermediate–mass–ratio inspirals (IMRIs), i.e., the inspirals of stellar mass compact object...
Estimation of C II and C II* column densities along Galactic sight-lines
ine profiles – ISM clouds – ISM abundances – ultraviolet ISM
2010/11/10
We present interstellar Cii (1334.5323°A) and Cii ∗ (1335.7077°A)column density measurements along 14 Galactic sight-lines. These sight-lines sample a variety of Galactic disk environments and i...
Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
compact binary coalescense rates short gamma-ray
2010/11/12
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...
On emission-line spectra obtained from evolutionary synthesis models II. Scale-relations and the estimation of mass dependences
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
Aims. In this paper we study the influence of the ionizing cluster mass on the emission line spectrum of Hii regions in order to determine the influence of low mass clusters on the integrated emission...
The SEGUE Stellar Parameter Pipeline. V. Estimation of Alpha-Element Abundance Ratios From Low-Resolution SDSS/SEGUE Stellar Spectra
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/5
We present a method for the determination of [alpha/Fe] ratios from low-resolution (R = 2000) SDSS/SEGUE stellar spectra.
Improving the Estimation of Star formation Rates and Stellar Population Ages of High-redshift Galaxies from Broadband Photometry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We explore methods to improve the estimates of star formation rates and mean stellar population ages from broadband photometry of high redshift star-forming galaxies. We use synthetic spectral templat...
Parameter estimation biases due to contributions from the Rees-Sciama effect to the integrated Sachs-Wolfe spectrum
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
The subject of this paper is an investigation of the nonlinear contributions to the spectrum of the integrated Sachs-Wolfe (iSW) effect. We derive the corrections to the iSW-auto spectrum and the iSW-...
Panchromatic Estimation of Star Formation Rates in BzK Galaxies at 1
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We determine Star Formation Rates (SFRs) in a sample of color selected, star forming (sBzK) galaxies (K(AB)<21.8) in the Extended Chandra Deep Field - South (ECDF-S).

Predicting the future from observable sequences of events in astrophysics I. Maximum Likelihood Estimation for a fixed number of parameters
astrophysics Maximum Likelihood
2009/5/27
Using analytical and numerical methods, estimates are given of future predictions in astrophysics that can be gathered from a sequence of observed events, for example for γ-ray bursts. Some general pr...
Standing Shocks around Black Holes and Estimation of Outflow Rates Santabrata Das & S. K.
accretion disk black hole physics outflows
2009/5/19
We self-consistently obtain shock locations in an accretion
flow by using an analytical method. One can obtain the spectral properties,
quasi-periodic oscillation frequencies and the outflowrates wh...
