http://www.redalyc.org/articulo.oa?id=57146052001
A new method is proposed to infer the Hubble constant H0 through the observed mean transmitted flux from high-redshift quasars and the baryon acoustic oscillations (BAOs). A semi-analytical model ...TESTING THE ISOTROPY OF THE HUBBLE EXPANSION
http://www.redalyc.org/articulo.oa?id=57146052010
We have used the Union2.1 SNIa compilation to search for possible Hubble expansion anisotropies, dividing the sky in 9 solid angles containing roughly the same number of SNIa, as well as in two Ga ...NEW GALERKIN OPERATIONAL MATRICES FOR SOLVING LANE-EMDEN TYPE EQUATIONS
http://www.redalyc.org/articulo.oa?id=57146052006
Lane-Emden type equations model many phenomena in mathematical physics and astrophysics, such as thermal explosions. This paper is concerned with intro - ducing third and fourth kind Chebyshev-Gal ...PIPE3D, A PIPELINE TO ANALYZE INTEGRAL FIELD SPECTROSCOPY DATA: II. ANALYSIS SEQUENCE AND CALIFA DATAPRODUCTS
http://www.redalyc.org/articulo.oa?id=57146052013
We present Pipe3D, an analysis pipeline based on the FIT3D fitting tool, developed to explore the properties of the stellar populations and ionized gas of integral field spectroscopy (IFS) data. P ...THE FORMATION MASS OF A BINARY SYSTEM VIA FRAGMENTATION OF A ROTATING PARENT CORE WITH INCREASING TOTAL MASS
http://www.redalyc.org/articulo.oa?id=57146052012
We present a set of numerical simulations of the gravitational collapse of a uniform and rotating core, in which azimuthal symmetric mass seeds are initially implemented in order to favor the form ...A METHOD FOR LOCAL RECTIFICATION OF 2MASS POSITIONS WITH
http://www.redalyc.org/articulo.oa?id=57146052011
We propose to locally rectify 2MASS with respect to UCAC4 in order to diminish the systematic differences between these catalogs. We develop a rectification method that starts computing the weight ...TIDAL SHEAR AND THE V1309 SCO MERGER
http://www.redalyc.org/articulo.oa?id=57146052008
We show that the observed decline in the orbital period of the merger candidate V1309 Sco could have been driven by tidal shear energy dissipation, E? S. This mechanism becomes relevant once the e ...STANDARD STARS FOR THE HIGH-VELOCITY AND METAL-POOR PROJECT AT SAN PEDRO MARTIR
http://www.redalyc.org/articulo.oa?id=57146052007
The main documentation for the primary and secondary standard stars used in the high-velocity and metal-poor stars project is presented. Observations were taken using the Str¨omgren-Crawford, uvby ...3D MODELING OF SPECTRA AND LIGHT CURVES OF HOT JUPITERS WITH PHOENIX; A FIRST APPROACH
http://www.redalyc.org/articulo.oa?id=57146052005
A detailed global circulation model was used to feed the PHOENIX code and calculate 3D spectra and light curves of hot Jupiters. Cloud free and dusty radiative fluxes for the planet HD179949b were ...UNVEILING NEW ASSOCIATIONS IN PUPPIS
http://www.redalyc.org/articulo.oa?id=57146052004
A combined photometric and polarimetric analysis of OB stars known from two searches of OB stars in the Puppis region resulted in the identification of a new OB association located at a distance o ...PIPE3D, A PIPELINE TO ANALYZE INTEGRAL FIELD SPECTROSCOPY DATA: I. NEW FITTING PHILOSOPHY OF FIT3D
http://www.redalyc.org/articulo.oa?id=57146052003
We present an improved version of FIT3D, a fitting tool for the analysis of the spectroscopic properties of the stellar populations and the ionized gas derived from moderate resolution spectra of ...HALO OCCUPATION DISTRIBUTIONS OF MODERATE X-RAY AGNS FORMED THROUGH MAJOR AND MINOR MERGERS IN A ?-CDM COSMOLOGY
http://www.redalyc.org/articulo.oa?id=57146052002
Motivated by the shape of the halo occupation distribution (HOD) of Xray selected AGNs in the COSMOS field recently inferred by Allevato et al., we investigated the HOD properties of moderate X-ra ...COSMOLOGICAL BOUNDS ON OPEN FLRW SOLUTIONS OF MASSIVE GRAVITY
http://www.redalyc.org/articulo.oa?id=57146052009
In this work we analysed some cosmological bounds concerning an open FLRW solution of massive gravity. The constraints from recent observationa l H ( z) data are found and the best fit values for ...
