A cosmic barbecue:Researchers spot 60 new ‘hot Jupiter’ candidates
A cosmic barbecue Researchers 60 new hot Jupiter candidates
2017/7/24
Yale researchers have identified 60 potential new “hot Jupiters” — highly irradiated worlds that glow like coals on a barbecue grill and are found orbiting only 1% of Sun-like stars.Hot Jupiters const...
A Critical Examination of Hypernova Remnant Candidates in M101. II. NGC 5471B
M101 kinematics and dynamics
2014/12/26
NGC 5471B has been suggested to contain a hypernova because of its extraordinarily bright X-ray emission. To assess its true nature, we have obtained high-resolution images in continuum bands and nebu...
XMM-Newton Spectra of Intermediate-Mass Black Hole Candidates: Application of a Monte Carlo Simulated Model
NGC 5408 NGC 628
2014/12/24
We present a systematic spectral analysis of six ultraluminous X-ray sources (NGC 1313 X-1 and X-2, IC 342 X-1, Ho IX X-1, NGC 5408 X-1, and NGC 3628 X-1) observed with the XMM-Newton observatory. The...
Electromagnetic follow-up of gravitational wave transient signal candidates
Electromagnetic follow-up gravitational wave transient signal candidates
2012/2/24
Pioneering efforts aiming at the development of multi-messenger gravitational wave and electromagnetic astronomy have been made. An electromagnetic observation follow-up program of candidate gravitati...
Photometric SN Ia Candidates from the Three-Year SDSS-II SN Survey Data
Photometric Candidates Three-Year SDSS-II SN Survey Data
2011/10/21
We analyze the three-year SDSS-II Superernova (SN) Survey data and identify a sample of 1070 photometric SN Ia candidates based on their multi-band light curve data. This sample consists of SN candida...
VLBI-selected sample of Compact Symmetric Object candidates and frequency-dependent position of hotspots
Galaxies: active – Galaxies: jets – Radio continuum: galaxies – Methods:numerical – Magnetohydrodynamics (MHD) – Shock waves
2011/9/27
The Compact Symmetric Objects (CSOs) are small (<1 kiloparsec) and powerful extragalactic radio sources showing emission on both sides of an active galactic nucleus and no signs of strong relativistic...
Context. In order to study the association of the origin of ultra high energy cosmic rays (UHECR) with active galactic nuclei (AGN) at all levels of their activity we require an unbiased sample of bla...
Discovery and identification of infrared counterpart candidates of four Galactic centre low mass X-ray binaries
X-rays: binaries – infrared: stars – X-rays: individuals: XTE J1637− 498, IGRJ17379− 3747, IGR J17585− 3057, GX9+1
2011/9/30
The near infrared (nIR)/optical counterparts of low mass X-ray binaries (LMXBs) are often observationally dim and reside in high source density fields which make their identification problematic; howe...
X-ray flare candidates in short gamma-ray bursts
gamma-ray: bursts – radiation mechanism: non-thermal –X-rays
2011/9/30
We present the first systematic study of X-ray flare candidates in short gamma-ray bursts (SGRBs) exploiting the large 6-year Swift database with the aim to constrain the physical nature of such fluct...
Cataclysmic Variables and Other Compact Binaries in the Globular Cluster NGC 362: Candidates from Chandra and HST
cataclysmic binaries close binary stars globular clusters X-ray binaries
2010/11/10
Highly sensitive and precise X-ray imaging from Chandra, combined with the superb spatial resolution of HST optical images, dramatically enhances our empirical understanding of compact binaries such a...
Stellar and substellar mass function of the young open cluster candidates Alessi 5 and beta Monocerotis
Stellar substellar mass young open cluster candidates beta Monocerotis
2010/11/10
Although the stellar and substellar populations have been studied in various young and old open clusters, additional studies in clusters in the age range from 5 to 100Myr is crucial (e.g. to give more...
A Large Catalogue of Ultraluminous X-ray Source Candidates in Nearby Galaxies
X-rays binaries black hole physics
2010/11/9
Since their discovery, Ultraluminous X-ray sources (ULXs) have attracted attention due to their combination of extreme luminosities and extra-nuclear locations. However, they are a fairly rare phenome...
The lack of intense Lyman~alpha in ultradeep spectra of z=7 candidates in GOODS-S: imprint of reionization?
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We present ultradeep optical spectroscopy obtained with FORS2 on VLT of seven Lyman-break galaxy (LBG) candidates at z>6.5 selected in the GOODS-S field from Hawk-I/VLT and WFC3/HST imaging. For one g...
The Initial Mass Function and Young Brown Dwarf Candidates in NGC 2264. IV. The Initial Mass Function and Star Formation History
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We have studied the star formation history and the initial mass function (IMF) using the age and mass derived from spectral energy distribution (SED) fitting and from color-magnitude diagrams. We also...
