New observations of black hole devouring a star reveal rapid disk formation（图）
New observations black hole devouring star rapid disk formation
2020/9/11
When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...
Giant Planets Carving Paths around Four Young Stars,ALMA Observations Suggest
Giant Planets Carving Paths Four Young Stars ALMA
2015/12/22
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found the clearest evidence yet that giant planets have recently formed around four young stars. These new worlds, each p...
THE SIZE EVOLUTION OF PASSIVE GALAXIES: OBSERVATIONS FROM THE WIDE FIELD CAMERA 3 EARLY RELEASE SCIENCE PROGRAM
red galaxies isolates galaxies
2014/12/22
We present results on the size evolution of passively evolving galaxies at 1 . z . 2 drawn from the Wide Field Camera 3 Early Release Science program. Our sample was constructed using an analog to the...
The LTHE LUMINOSITY, MASS, AND AGE DISTRIBUTIONS OF COMPACT STAR CLUSTERS IN M83 BASED ON HUBBLE SPACE TELESCOPE/WIDE FIELD CAMERA 3 OBSERVATIONS
filters binning
2014/12/20
The newly installed Wide Field Camera 3 (WFC3) on the Hubble Space Telescope has been used to obtain multi-band images of the nearby spiral galaxy M83. These new observations are the deepest and highe...
Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
Fermi-LAT Observations Diffuse Gamma-Ray Emission Implications Cosmic Rays the Interstellar Medium
2012/2/23
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissio...
Observations and Analysis of High-Resolution Magnetic Field Structures in Molecular Clouds
Observations Analysis High-Resolution Magnetic Field Structures Molecular Clouds
2012/2/23
Recent high-angular-resolution (up to 0.7") dust polarization observations toward star forming regions are summarized. With the Sub-Millimeter Array, the emission from the dense structures is traced a...
First Science Observations with SOFIA/FORCAST: 6 to 37 micron Imaging of the Central Orion Nebula
First Science Observations SOFIA/FORCAST micron Central Orion Nebula
2012/2/23
We present new mid-infrared images of the central region of the Orion Nebula using the newly commissioned SOFIA airborne telescope and its 5 -- 40 micron camera FORCAST. The 37.1 micron images represe...
Radio continuum observations of new radio halos and relics from the NVSS and WENSS surveys
Radio Continuum: galaxies – Galaxies: Clusters: general, intracluster medium – Cosmology: large-scale structure of Universe
2011/10/20
Radio halos and relics are diffuse radio sources found in galaxy clusters showing significant substructure at X-ray wavelengths. These sources provide important information about non-thermal processes...
X-rays and hard UV radiation From the First Galaxies: Ionization Bubbles and 21 cm Observations
stars: Population III. galaxies: high-redshift. (galaxies:) quasars: general. galaxies: star formation. cosmology: theory. (cosmology:) dark ages, reionization, rst stars
2011/10/9
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light ...
Star-forming Region Sh 2-233IR I. Deep NIR Observations toward the Embedded Stellar Clusters
Star-forming Sh 2-233IR Observations Embedded Stellar Clusters
2011/10/9
We observed the Sh 2-233IR (S233IR) region with better sensitivity in near-infrared than previous studies for this region. By applying statistical subtraction of the back- ground stars, we identified ...
GOODS-Herschel Measurements of the Dust Attenuation of Typical Star-Forming Galaxies at High Redshift: Observations of UV-Selected Galaxies at z~2
Dust Attenuation Typical Star-Forming Galaxies High Redshift: Observations Galaxies
2011/10/9
We take advantage of the sensitivity and resolution of Herschel at 100 and 160 micron to directly image the thermal dust emission and investigate the infrared luminosities, L(IR), and dust obscuration...
SuperWASP observations of pulsating Am stars
Asteroseismology – Stars:chemically peculiar – Stars:oscillations – Stars:variables:delta Scuti – Techniques:photom- etry
2011/9/27
We have studied over 1600 Am stars at a photometric precision of 1 mmag with SuperWASP photometric data. Contrary to previous belief, we find that around 200 Am stars are pulsating delta Sct and gamma...
