Sky survey reveals newborn jets in distant galaxies（图）
Sky survey newborn jets distant galaxies
2020/12/11
Astronomers using data from the ongoing VLA Sky Survey have found distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material w...
The clustering dipole of the local universe from the Two Micron All Sky Survey
galaxies clusters
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for investigating the galaxies populating the local universe. A full charact...
A Two Micron All Sky Survey view of the Sagittarius dwarf galaxy. I. Morphology of the Sagittarius core and tidal arms
the Sagittarius core tidal arms
2014/12/24
We present the first all-sky view of the Sagittarius (Sgr) dwarf galaxy mapped by M-giant star tracers detected in the complete Two Micron All Sky Survey (2MASS). Near-infrared photometry of Sgr's pro...
A Two Micron All Sky Survey view of the Sagittarius dwarf galaxy. II. Swope telescope spectroscopy of M giant stars in the dynamically cold Sagittarius tidal stream
kinematics halo
2014/12/24
We have obtained moderate resolution (~6 km s-1) spectroscopy of several hundred M giant candidates selected from Two Micron All Sky Survey photometry. Radial velocities are presented for stars mainly...
The galaxy angular correlation functions and power spectrum from the Two Micron All Sky Survey
general statistics
2014/12/24
We calculate the angular correlation function of galaxies in the Two Micron All Sky Survey. We minimize the possible contamination by stars, dust, seeing, and sky brightness by studying their cross co...
Nature and completeness of galaxies detected in the Two Micron All Sky Survey
surveys general fundamental parameters.
2014/12/24
The Two Micron All Sky Survey (2MASS) provides the most comprehensive data set of near-infrared galaxy properties. We cross correlate the well-defined and highly complete spectroscopic selection of ov...
COLOR-MAGNITUDE RELATION AND MORPHOLOGY OF LOW-REDSHIFT ULIRGs IN SLOAN DIGITAL SKY SURVEY
color-magnitude morphological analysis
2014/12/20
We present color-magnitude and morphological analysis of 54 low-redshift ultraluminous infrared galaxies (ULIRGs; 0.018 < z < 0.265 with z median = 0.151), a subset of the Infrared Astronomical Satell...
A SEARCH FOR RADIO PULSARS IN THE NORTHERN SKY: DISCOVERY OF A PULSAR IN A UNIQUE BINARY SYSTEM
Search Radio pulsar The sky The pulsar. A binary system
2014/12/10
A sensitive search for pulsars has been conducted using the 92-meter transit telescope of the National Radio Astronomy Observatory. Nearly 50% of the sky north of +20(DEGREES) declination was searched...
Avoiding bias in reconstructing the largest observable scales from partial-sky data
Avoiding bias reconstructing largest observable partial-sky data
2011/10/18
Obscuration due to Galactic emission complicates the extraction of information from cosmological surveys, and requires some combination of the (typically imperfect) modeling and subtraction of foregro...
A Catalog of Bulge+Disk Decompositions and Updated Photometry for 1.12 Million Galaxies in the Sloan Digital Sky Survey
Decompositions Updated Photometry Galaxies Sloan Digital
2011/9/29
We perform two-dimensional, Point-Spread-Function-convolved, bulge+disk decompositions in the $g$ and $r$ bandpasses on a sample of 1,123,718 galaxies from the Legacy area of the Sloan Digital Sky Sur...
