Mapping plasma structures in the high-latitude ionosphere using beacon satellite, incoherent scatter radar and ground-based magnetometer observations
Beacon satellites ionospheric plasma
2015/9/25
In the autumn of the year 2000, four radio receivers capable of tracking various beacon satellites were set up along the southwestern coast of Greenland. They are used to reconstruct images of the ion...
A revised method to extract thermospheric parameters from incoherent scatter observations
thermospheric ionization
2015/9/14
Height distribution of ionospheric plasma parameters in the F2-region is closely related to height distribution of the main thermospheric parameters. Therefore, they can be extracted from ionospheric ...
Merger induced scatter and bias in the cluster mass - Sunyaev-Zeldovich effect scaling relation
cosmology: large-scale structure of Universe, galaxies: clusters: general, meth- ods: N-body simulations
2011/10/20
We examine sources of scatter in scaling relations between galaxy cluster mass and thermal Sunyaev-Zeldovich (SZ) effect using cluster samples extracted from cosmological hydrodynamical simulations. O...
A More General Model for the Intrinsic Scatter in Type Ia Supernova Distance Moduli
General Model Intrinsic Scatter Supernova Distance Moduli
2011/10/13
We describe a new formalism to fit the parameters $\alpha$ and $\beta$ that are used in the SALT2 model to determine the standard magnitudes of Type Ia supernovae. The new formalism describes the intr...
Particle‐in‐cell simulation of incoherent scatter radar spectral distortions related to beam‐plasma interactions in the auroral ionosphere
incoherent scatter radar auroral ionosphere
2017/3/22
An electrostatic parallel particle‐in‐cell (EPPIC) code that allows for particle beam
injections and multiple boundary conditions is used to investigate the beam‐plasma
interaction and its manifesta...
Disk Galaxy Scaling Relations in the SFI++: Intrinsic Scatter and Applications
galaxies spirals – galaxies fundamental parameters – galaxies
2010/11/15
We study the scaling relations between the luminosities, sizes, and rotation velocities of disk galaxies in the SFI++, with a focus on the size-luminosity (RL) and size-rotation velocity (RV ) relatio...
The Impact of Cluster Structure and Dynamical State on Scatter in the Sunyaev-Zel'dovich Flux-Mass Relation
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
Cosmological constraints from cluster surveys rely on accurate mass estimates from the mass-observable relations. In order to avoid systematic biases and reduce uncertainties, we study the form and ph...
Impact of brown and clear carbon on light absorption enhancement, single scatter albedo and absorption wavelength dependence of black carbon
brown and clear carbon light absorption enhancement single scatter albedo black carbon
2010/8/12
The presence of clear coatings on atmospheric black carbon (BC) particles is known to enhance the magnitude of light absorption by the BC cores. Based on calculations using core/shell Mie theory, we d...
Analysis of beam plasma instability effects on incoherent scatter spectra

Naturally Enhanced Ion Acoustic Lines (NEIALs)
detected with Incoherent Scatter Radars (ISRs) can be produced
by a Langmuir decay mechanism, triggered by a bump
on tail instability. A recent model ...
Accurate AGN black hole masses and the scatter in the M_{bh} - L_{bulge} relationship
black hole physics galaxies active galaxies bulges galaxies fundamental parameters galaxies nuclei quasars emission lines
2010/3/9
A new empirical formulae is given for estimating the masses of black holes in AGNs from the H beta velocity dispersion and the continuum luminosity at 5100 Angstroms. It is calibrated to reverberation...
Limb scatter ozone retrieval from 10 to 60 km using a multiplicative algebraic reconstruction technique
Limb scatter ozone multiplicative algebraic reconstruction technique
2009/9/14
The OSIRIS instrument onboard the Odin spacecraft routinely measures vertical profiles of spectrally dispersed, limb scattered sunlight from the upper troposphere into the lower mesosphere. These meas...
