On the relation between Seyfert 2 accretion rate and environment at z < 0.1 [PDF]

open access: yes, 2014
We analyse different properties of the small-scale environment of Seyfert 2 for two samples selected according to the accretion rate parameter, R, from the Sloan Digital Sky Survey, Data Release 7 survey.

The apparent overdensity of open clusters in the Canis Major overdensity [PDF]

open access: yes, 2008
The exciting debate on the existence and nature of the relatively recent discovery of the so-called Canis Major (CMa) overdensity is re-examined here based on the positions, reddenings, ages and metallicities of Galactic open clusters (OCs).

Clues on void evolution II: Measuring density and velocity profiles on SDSS galaxy redshift space distortions [PDF]

open access: yes, 2013
Using the redshift-space distortions of void-galaxy cross-correlation function we analyse the dynamics of voids embedded in different environments. We compute the void-galaxy crosscorrelation function in the Sloan Digital Sky Survey (SDSS) in terms of ...

Are CMEs capable of producing Moreton waves? A case study: The 2006 December 6 event [PDF]

open access: yes, 2018
Considering the chromosphere and a stratified corona, we examine, by performing 2D compressible magnetohydrodynamics simulations, the capability of a coronal mass ejection (CME) scenario to drive a Moreton wave. We find that given a typical flux rope (FR)

Observatorios Culturales

open access: yesPeriferica, 2013
El debate acerca de la importancia de medir la cultura como elemento de las políticas públicas parece estar de nuevo de actualidad. Sin prejuicio de defender, o no, la existencia de los «observatorios culturales », el presente texto pretende esbozar un rápido cuadro de la situación, pasada y actual, sobre la cuestión de la medición de la cultura para ...

Environment of 1 ≤ z ≤ 2 MIR selected obscured and unobscured AGNs in the Extended Chandra Deep Field South [PDF]

open access: yes, 2017
Context. In unified models, different types of active galaxy nuclei (AGN) correspond to a single class of objects, where their observed differences are solely due to the different orientations of the obscuring material around the central inner regions ...

Multi-line modelling in nearby galaxies: The link between dense gas and star formation in different environments [PDF]

open access: yesEPJ Web of Conferences, 2022
The J=1–0 lines of HCN and HCO+ have become the default tracers of dense molecular gas in external galaxies. To study the relation between HCN and HCO+ emission and density, we have mapped their J=3–2 lines with the ALMA Compact Array (ACA) in the nearby
