Gemini Tracks Distant Star Cluster with Adaptive Optics
Gemini Distant Star Cluster Adaptive Optics
2017/7/20
We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a baseline of ～ 5 yea...
Adaptive optics assisted near-infrared polarization measurements of sources in the Galactic Center
Galaxy: center - Polarization - dust, extinction - Infrared: stars
2011/10/11
The goals of this work are to provide NIR polarimetry of the stellar sources in the central pc at the resolution of an 8m telescope for the first time, along with new insights into the nature of the k...
Adaptive gravitational softening in GADGET
gravitation – methods: numerical – cosmology: theory, large-scale struc- ture of Universe
2011/10/9
Cosmological simulations of structure formation follow the collisionless evolution of dark matter starting from a nearly homogeneous field at early times down to the highly clustered configuration at ...
Adaptive image ray-tracing for astrophysical simulations
Adaptive image ray-tracing astrophysical simulations
2011/1/11
A technique is presented for producing synthetic images from numerical simulations whereby the image resolution is adapted around prominent features. In so doing, adaptive image ray-tracing (AIR) impr...
N-body Simulations for f(R) Gravity using a Self-adaptive Particle-Mesh Code
N-body Simulations Self-adaptive Particle-Mesh Code
2010/11/11
We perform high resolution N-body simulations for f(R) gravity based on a self-adaptive particle-mesh code MLAPM. The Chameleon mechanism that recovers General Relativity on small scales is fully take...
The properties of Brightest Cluster Galaxies in the SDSS DR6 adaptive matched filter cluster catalogue
galaxies: clusters general – galaxies elliptical and lenticular
2010/11/15
We study the properties of Brightest Cluster Galaxies (BCGs) drawn from a catalogue of more than 69000 clusters in the SDSS DR6 based on the adaptive matched filter technique (AMF, Szabo et al., 2010)...
An Optical Catalog of Galaxy Clusters Obtained from an Adaptive Matched Filter Finder Applied to SDSS DR6
Optical Catalog of Galaxy Clusters Obtained Adaptive Matched Filter Finder Applied
2010/11/9
We present a new cluster catalog extracted from the Sloan Digital Sky Survey Data Release 6 (SDSS DR6) using an adaptive matched filter (AMF) cluster finder. We identify 69,173 galaxy clusters in the ...
Radiative cooling in numerical astrophysics: the need for adaptive mesh refinement
Computational techniques fluid dynamics Radiative recombination Radiative transfer in astrophysics
2010/11/15
Energy loss through optically thin radiative cooling plays an important part in the evolution of astrophysical gas dynamics and should therefore be considered a necessary element in any numerical simu...
RFI mitigation with phase-only adaptive beamforming
RFI mitigation phase-only adaptive beamforming
2010/11/12
Connected radio interferometers are sometimes used in the tied-array mode:signals from antenna elements are coherently added and the sum signal applied to a VLBI backend or pulsar processing machine. ...
The Durham adaptive optics real-time controller
Instrumentation and Methods for Astrophysics (astro-ph.IM) Instrumentation and Detectors (physics.ins-det)
2011/1/6
The Durham adaptive optics real-time controller was initially a proof of concept design for a generic adaptive optics control system. It has since been developed into a modern and powerful CPU based r...
The Magellan Adaptive Secondary VisAO Camera: Diffraction- Limited Broadband Visible Imaging and 20mas Fiber Array IFS
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
The Magellan Adaptive Secondary AO system, scheduled for first light in the fall of 2011, will be able to simultaneously perform diffraction limited AO science in both the mid-IR, using the BLINC/MIRA...
