The Anatomy of Galaxies

, 2016
Just after WWII Astronomy started to live its "Golden Age", not differently to many other sciences and human activities, especially in the west side countries. The improved resolution of telescopes and the appearance of new efficient light detectors (e.g. CCDs in the middle eighty) greatly impacted the extragalactic researches.

Are brightest halo galaxies central galaxies? [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
It is generally assumed that the central galaxy in a dark matter halo, that is, the galaxy with the lowest specific potential energy, is also the brightest halo galaxy (BHG), and that it resides at rest at the centre of the dark matter potential well. This central galaxy paradigm (CGP) is an essential assumption made in various fields of astronomical ...

Photovoltaic and Photomultiplication Dual‐Mode Near‐Infrared Organic Detectors with Large Dynamic Range for Intensive and Faint Light Sensing

Advanced Science, EarlyView.
A photovoltaic/photomultiplication dual‐mode organic photodetector is developed by integrating two different organic bulk‐heterojunctions, one introduces the photovoltaic effect, and the other triggers photomultiplication charge generation in the stacked device at different voltage polarities.

A search for disk-galaxy lenses in the Sloan Digital Sky Survey

, 2009
We present the first automated spectroscopic search for disk-galaxy lenses, using the Sloan Digital Sky Survey database. We follow up eight gravitational lens candidates, selected among a sample of ~40000 candidate massive disk galaxies, using a ...

Identifying dynamically young galaxy groups via wide-angle tail galaxies: A case study in the COSMOS field at z=0.53 [PDF]

, 2010
We present an analysis of a wide-angle tail (WAT) radio galaxy located in a galaxy group in the COSMOS field at a redshift of z=0.53 (hereafter CWAT-02).

INTERACTIONS OF GALAXIES IN THE GALAXY CLUSTER ENVIRONMENT [PDF]

The Astrophysical Journal, 2009
We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the SDSS galaxies associated with the Abell galaxy clusters. We find that there exists a characteristic scale where the properties of galaxies suddenly start to depend on the clustercentric radius at fixed ...

A Review of Ga₂O₃ Heterojunctions for Deep‐UV Photodetection: Current Progress, Methodologies, and Challenges

Advanced Electronic Materials, EarlyView.
This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges
