Astronomers evidence Einstein theories star orbiting massive black hole
2019/10/22
More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such powerful effects on Earth. Instead, astronomers turn their att...
IDENTIFICATION OF A COMPLETE 160 μm FLUX-LIMITED SAMPLE OF INFRARED GALAXIES IN THE ISO LOCKMAN HOLE 1 deg2 DEEP FIELDS: SOURCE PROPERTIES AND EVIDENCE FOR STRONG EVOLUTION IN THE FIR LUMINOSITY FUNCTION FOR ULIRGs
starburst-active galactic nucleus (AGN) composite AGN spectral types
2014/12/20
We have identified a complete, flux-limited (S 160>120 mJy) sample of 160 μm selected sources from Spitzer observations of the 1 deg2 Infrared Space Observatory (ISO) Deep Field region in the Lockman ...
EVIDENCE FOR 1000 km s–1 MOLECULAR OUTFLOWS IN THE LOCAL ULIRG POPULATION
star formation history,
2014/12/20
The feedback from galactic outflows is thought to play an important role in shaping the gas content, star formation history, and ultimately the stellar mass function of galaxies. Here we present evide...
Evidence for top-heavy stellar initial mass functions with increasing density and decreasing metallicity
formation mass-functionlatetype globular clusters general top-heavy stellar metallicity
2012/2/23
Residual-gas expulsion after cluster formation has recently been shown to leave an imprint in the low-mass present-day stellar mass function (PDMF) which allowed the estimation of birth conditions of ...
Evidence for Multiple Pathways to Deuterium Enhancements in Protoplanetary Disks
Evidence Multiple Pathways Deuterium Enhancements Protoplanetary Disks
2012/2/23
The distributions of deuterated molecules in protoplanetary disks are expected to depend on the molecular formation pathways. We use observations of spatially resolved DCN emission from the disk aroun...

Evidence for Inflow in High-Mass Star-Forming Clumps
2011/10/17
We analyze the HCO+ 3-2 and H13CO+ 3-2 line profiles of 27 high-mass star-forming regions to identify asymmetries that are suggestive of mass inflow. Three quantitative measures of line asymmetry are ...
'Best evidence yet' for dark matter comes from Milky Way centre（图）
dark matter Milky Way centre
2010/12/1
Energetic radiation pulsing from the belly of the Milky Way is the clearest signal yet of dark matter. That is according to a pair of astrophysicists in the US who reach this conclusion after scrutini...
SGRs and AXPs：Evidence for Delayed Amplification of Magnetic Field after Neutron Star Formation?
Anomalous X-ray Pulsars soft gamma-ray repeaters supernova remnants
2009/9/4
We present new analysis of the birth rate of AXPs and SGRS and their associated SNRs. Using Kolmogorov-Smirnov statistics together with parametric fits based on a robust estimator, we find a birth rat...

QSO Pairs across Active Galaxies: Evidence of Blueshifts?
Quasars: emission lines quasars: absorption lines cosmology: miscellaneous
2009/5/7
Several QSO pairs have been reported and their redshifts determined, where the two objects in each pair are located across an active galaxy. The usually accepted explanation of such occurrences is tha...
16 May 2007，A ring-shaped distribution of mass in a galaxy cluster five billion light-years from Earth is the strongest evidence yet for the existence of dark matter. This is the claim of physicists f...
