From the Blazar Sequence to the Blazar Envelope: Revisiting the Relativistic Jet Dichotomy in Radio-loud AGN
Blazar Envelope Revisiting Relativistic Jet Dichotomy Radio-loud AGN
2011/10/21
We revisit the concept of a blazar sequence that relates the synchrotron peak frequency ({\nu}peak) in blazars with synchrotron peak luminosity (Lpeak, in {\nu}L{\nu}) using a large sample of radio-lo...
Revisiting the solar tachocline: Average properties and temporal variations
Revisiting solar tachocline:Average properties temporal variations
2011/9/28
The tachocline is believed to be the region where the solar dynamo operates. With over a solar cycle's worth of data available from the MDI and GONG instruments, we are in a position to investigate no...

Minkowski famously introduced the concept of a space-time continuum in 1908, merging three dimensional space with an imaginary time dimension represented by ict, a framework which naturally produced t...
γ-ray properties of the CJF sample: Revisiting the beaming hypothesis
γ-ray properties the CJF sample
2011/1/10
The recent release of the First Fermi-LAT Source Catalog solidified the predominant association of extragalactic {\gamma}-ray emitters to active galaxies, in particular blazars. A tight connection bet...
Revisiting the Flowers-Ruderman instability of magnetic stars
magnetic fields MHD – stars magnetic field
2010/11/10
In 1977, Flowers and Ruderman described a perturbation that destabilises a purely
dipolar magnetic field in a fluid star. They considered the effect of cutting the star
in half along a plane contain...
Revisiting with Chandra the Scaling Relations of the X-ray Emission Components (Binaries, Nuclei and Hot Gas) of Early Type Galaxies
galaxies elliptical and lenticular – X-rays galaxies
2010/11/15
We have selected a sample of 30 normal (non-cD) early type galaxies, for all of which optical spectroscopy is available, and which have been observed with Chandra to a depth such to insure the detecti...
Revisiting the Hubble sequence in the SDSS DR7 spectroscopic sample: a publicly available bayesian automated classification
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/5
We present an automated morphological classification in 4 types (E,S0,Sab,Scd) of ~700.000 galaxies from the SDSS DR7 spectroscopic sample based on support vector machines. The main new property of th...
The characteristics of planetary wave energy propagation are being compared based on NCEP reanalysis data from 1958 to 2002 between boreal winters after strong volcanic eruptions, non-volcanic winters...
Revisiting silicate authigenesis in the Pliocene–Pleistocene Lake Tecopa beds, southeastern California: Depositional and hydrological controls
saline, alkaline lake, Pliocene–Pleistocene, zeolite, depositional facies, authigenic minerals
2011/11/14
The Pliocene–Pleistocene Lake Tecopa beds present a well-documented example of authigenic silicate diagenesis in an ancient saline, alkaline lake environment. Controls on authigenic mineral formation ...
Between De Jure and De Facto Statehood: Revisiting the Status Issue for Taiwan
Taiwan, China statehood sovereignty de facto states self-determination secession
2010/9/13
This paper revisits the status prospects for Taiwan in light of recent events in Kosovo and Tibet. In both cases, and certainly in Taiwan itself, the long standing contest between claims for self dete...

Revisiting the First-Principles Approach to the Granular Gas Steady State
the First-Principles Approach the Granular Gas Steady State
2010/10/26
We extend a Fokker-Planck formalism, previously used to describe the behavior of a cooling granular gas, with a Hertzian contact potential and viscoelastic radial friction, giving a velocity dependent...
