1 billion suns:World’s brightest laser sparks new behavior in light
1 billion suns World’s brightest laser sparks in light
2017/7/24
By focusing laser light to a brightness 1 billion times greater than the surface of the sun — the brightest light ever produced on Earth — the physicists have observed changes in a vision-enabling int...
Called SN 2014J, the glowing supernova was discovered by a professor and his students in the United Kingdom on Jan. 21, about a week after the stellar explosion first became visible as a pinprick of l...
The luminosities of the brightest cluster galaxies and brightest satellites in SDSS groups
galaxies: luminosity function
2011/10/11
We show that the distribution of luminosities of Brightest Cluster Galaxies, in two SDSS-based group catalogs, suggests that BCG luminosities are just the statistical extremes of the group galaxy lumi...
A deep spectroscopic study of the filamentary nebulosity in NGC4696, the brightest cluster galaxy in the Centaurus cluster
galaxies: clusters: individual: Centaurus - galaxies: cooling fl ows - galaxies:individual: NGC 4696
2011/10/12
We present results of deep integral field spectroscopy observations using high resolution optical (4150-7200 A) VIMOS VLT spectra, of NGC 4696, the dominant galaxy in the Centaurus cluster (Abell 3526...
The properties of Brightest Cluster Galaxies in the SDSS DR6 adaptive matched filter cluster catalogue
galaxies: clusters general – galaxies elliptical and lenticular
2010/11/15
We study the properties of Brightest Cluster Galaxies (BCGs) drawn from a catalogue of more than 69000 clusters in the SDSS DR6 based on the adaptive matched filter technique (AMF, Szabo et al., 2010)...
Exploring the Nature of the Brightest Hyper-luminous X-ray Source
accretion accretion disks – X-rays binaries – X-rays individual (ESO 243-49 HLX-1)
2010/11/11
The small subset of hyper-luminous X-ray sources with luminosities in excess of 1041 erg s−1 are hard to explain without the presence of an intermediate mass black hole, as significantly super-...

State’s brightest attracted to University of Queensland neuroscience challenge
neuroscience
2007/3/12
12 March 2007，Sixty-five of Queensland's brightest Year 11 students will compete for more than $25,000 in prizes as part of Australia's most prestigious neuroscience competition for high schools at UQ...
18 January 2007，The bright colours of certain insects are normally down to either a strong pigmentation or a highly periodic structure. But these properties cannot be responsible for insects with bril...
