A census of compact sources at 162 MHz: First data release from the MWA Phase II IPS Survey

نویسندگان

چکیده

We present a catalogue of over 7000 sources from the GLEAM survey which have significant structure on sub-arcsecond scales at 162MHz. The compact nature these was detected and quantified via their Interplanetary Scintillation (IPS) signature, measured in interferometric images Murchison Widefield Array. advantage this approach is that all sufficiently across area are included down to well-defined flux density limit. based $\sim$250$\times$ 10-minute observations, covered somewhat irregular, but within 1hr5\sigma$ confidence), with further 5550 tentative ($>2\sigma$ confidence) detections. Normalised Indices (NSI; measure fraction coming component) reported sources. Robust informative upper limits NSI 31081 This represents largest radio frequencies ever undertaken.

Compact Structure in FIRST Survey Sources

We present preliminary results from a statistical survey of compact structure in faint radio sources. Around 1000 sources from the VLA FIRST survey (flux densities ≥ 1 mJy at 1.4 GHz) have been observed with the single-baseline interferometer Effelsberg-Arecibo. We observed each source, selected from a narrow strip of sky at declination 28, for just one minute. The baseline sensitivity at 1.4 G...

The Pearson-readhead Survey of Compact Extragalactic Radio Sources from Space. Ii. Analysis of Source Properties

We have performed a multi-dimensional correlation analysis on the observed properties of a statistically complete core-selected sample of compact radio-loud active galactic nuclei, based on data from the VLBI Space Observing Programme (Paper I) and previously published studies. Our sample is drawn from the well-studied Pearson-Readhead (PR) survey, and is ideally suited for investigating the ge...

The DPOSS II compact group survey: first spectroscopically confirmed candidates

Context. This paper presents the results of a pilot redshift survey of 18 candidate compact groups from the distant DPOSS survey that extends the available surveys of compact groups of galaxies to z ∼ 0.2 in redshift, mainly Hickson Compact Groups and Southern Compact Groups. Aims. The goal of our survey was to confirm group membership via redshift information and to measure the characteristic ...

A survey of Low Luminosity Compact sources

Based on the FIRST and SDSS catalogues a flux density limited sample of weak Compact Steep Spectrum (CSS) sources with radio luminosity below 1026 W Hz−1 at 1.4 GHz has been constructed. Our previous multifrequency observations of CSS sources have shown that low luminosity small-scale objects can be strong candidates for compact faders. This finding supports the idea that some small-size radio ...
