Magpis: a Multi-array Galactic Plane Imaging Survey
We present the Multi-Array Galactic Plane Imaging Survey (MAGPIS), which maps portions of the first Galactic quadrant with an angular resolution, sensitivity and dynamic range that surpasses existing radio images of the Milky Way by more than an order of magnitude. The source detection threshold at 20 cm is in the range 1-2 mJy over the 85% of the survey region (5 < l < 32, |b|< 0.8) not covere...
متن کاملVLA-GBT Wide-band Galactic Plane Survey
In this white paper we discuss strategies for a wide-band continuum and spectral line galactic plane survey in the l-band exploiting the power of the vla’s widar correlator for simultaneous high resolution observations of the h 21cm line, all four oh transitions, 18 radio recombination lines (both h and c), and the 1066mhz transition of formaldehyde. All other existing surveys of the galactic...
متن کاملThe EVN Galactic Plane Survey – EGaPS
I present a catalogue of the positions and correlated flux densities of 109 compact extragalactic radio sources in the Galactic plane determined from an analysis of a 48-h Very Long Baseline Interferometry (VLBI) experiment at 22 GHz with the European VLBI Network. The median position uncertainty is 9 mas. The correlated flux densities of the detected sources are in the range of 20–300 mJy. In ...
متن کاملLine Survey Observations of the Galactic Plane
We present results of our survey observations of the [C II] 158 μm line emission from the Galactic plane using the Balloon-borne Infrared Carbon Explorer (BICE). Our survey covers a wide area (350◦∼< l ∼< 25, |b| ∼< 3) with a spatial resolution of 15. We employed a new observing method called the “fast spectral scanning” to make large-scale observations efficiently. Strong [C II] line emission ...
متن کاملFirst Year Project Report — Part 1 . Where are the Clumps ? Neil Zimmerman
The NE2001 model for the free electron distribution of the Milky Way includes ad hoc electron “clumps” to reconcile line of sight observables with basic model predictions (Cordes et al. 2002). While MAGPIS (Multi-Array Galactic Plane Imaging Survey) is insensitive to emission from individual diffuse HII regions (ne ∼10 cm), by investigating the 20 cm maps we are able to verify their assumption ...
