Black holes make for a great space mystery. They're so massive that nothing, not even light, can escape a black hole once it gets close enough. A great mystery for scientists is that there's evidence ...
AzTEC Millimetre Survey of the COSMOS Field: I. Data Reduction and Source Catalogue
starburst submillimetre
2014/12/23
We present a 1.1 mm wavelength imaging survey covering 0.3 deg2 in the COSMOS field. These data, obtained with the AzTEC continuum camera on the James Clerk Maxwell Telescope, were centred on a promin...
STAR FORMATION RATES IN LYMAN BREAK GALAXIES: RADIO STACKING OF LBGs IN THE COSMOS FIELD AND THE SUB-mu Jy RADIO SOURCE POPULATION
formation evolution
2014/12/23
We present an analysis of the radio properties of large samples of Lyman break galaxies (LBGs) at z ~ 3, 4, and 5 from the COSMOS field. The median stacking analysis yields a statistical detection of ...
The Chandra COSMOS Survey (C-COSMOS) is a large, 1.8 Ms, Chandra program that has imaged the central 0.5 deg2 of the COSMOS field (centered at 10 h , +02 o ) with an effective exposure of ~160 ks, and...
AzTEC Millimetre Survey of the COSMOS field - II. Source count overdensity and correlations with large-scale structure
galaxies submillimeter gravitational lensing
2014/12/22
We report an overdensity of bright submillimetre galaxies (SMGs) in the 0.15 deg2 AzTEC/COSMOS survey and a spatial correlation between the SMGs and the optical-IR galaxy density at z≲ 1.1. This...
THE REDSHIFT AND NATURE OF AzTEC/COSMOS 1: A STARBURST GALAXY AT z = 4.6*
broadband narrowband photometry
2014/12/20
Based on broadband/narrowband photometry and Keck DEIMOS spectroscopy, we report a redshift of z = 4.64+0.06 –0.08 for AzTEC/COSMOS 1, the brightest submillimeter galaxy (SMG) in the AzTEC/COSMOS fiel...
Full revision of“单元纯系宇宙”and "Homogenous Cosmos Originated from Unique Genesis
PNT惠合系 单元纯系宇宙
2015/6/4
作为认识历史延续,“单元纯系宇宙”是从传统科学有关“物质微观结构趋同性”认识积蓄中延伸出来的“宇宙重认识和重定义”,——源自“宇宙单元纯系假设”、关于整个宇宙构造及其宇宙物质性存在与运动变化的“单一线性逻辑体系”。它将传统科学有关“物质微观结构趋同性”认识积蓄兑现至“宇宙单元纯系假设”,继而将宇宙内涵“时空”与“物质”代入“宇宙单元纯系假设”,导出时空与物质间的纯系性“PNT关系(或PNT行为)”...
Two fossil groups of galaxies at z~0.4 in the COSMOS: accelerated stellar-mass build-up, different progenitors
X-rays: galaxies: clusters – galaxies: groups: general – galaxies: evolution – galaxies: luminosity function, mass function
2011/10/12
We report on 2 fossil groups of galaxies at z=0.425 and 0.372 discovered in the Cosmic Evolution Survey (COSMOS) area. Selected as X-ray extended sources, they have total masses (M_200) of 1.9(+/-0.41...
Herschel and Planck Missions to Study Cosmos Share Ride to Space
Herschel and Planck Cosmos Space
2009/5/7
Herschel and Planck are both ESA missions with important participation from NASA. NASA's Herschel Project Office and Planck Project Office are both based at JPL. A consortium of European-led institute...
Development of the concept of fractal cosmos after Anaxagoras has
been followed up to the present. It is shown how the concept reappeared in the
early Renaissance as a vague idea and subsequently to...
We consider Einstein's attitude regarding religious as such, from
both cosmological and epistemological points of view. An attempt to put it into
a wider socio-historical perspective was made, with ...
