Bar And Spiral Structure Legacy (BeSSeL) Survey Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 25, 2016
The BeSSeL Survey is a Very Long Baseline Array (VLBA) key science project whose goal is to study the kinematics and spiral structure of the Milky Way Galaxy. They do this by measuring the trigonometric parallaxes and proper motions of masers associated with high-mass star forming regions throughout the Galaxy. The main maser emission lines include...
The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) is composed of several individual surveys and together they provide almost complete longitudinal coverage of the Galactic plane at |b| <= 1.0°. Most of the plane is imaged at a spatial resolution of <2” at wavelengths of 3.6, 4.5, 5.8, and 8.0 μm; however, certain longitudes in...
UKIRT Infrared Deep Sky Galactic Plane Survey (UKIDSS-GPS) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The UKIRT Infrared Deep Sky Galactic Plane Survey (UKIDSS-GPS) is a near infrared survey which will map over 1800 square degrees of the Galactic plane in J,H,K bands (1-3 μm) to a depth of 19 magnitudes. It is a successor to the 2MASS survey, probing 3 magnitudes deeper. The GPS plans to map half the plane over the following regions: 141° < l < 230...
Galactic Plane Infrared Polarization Survey (GPIPS) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The Galactic Plane Infrared Polarization Survey (GPIPS) covers 76 sq. deg in the Galactic midplane between 18° <= l <= 56° and -1° <= b <= +1°. It uses H-band (1.6 microns) linear polarimetry to determine magnetic field orientations in the plane of the sky near dense molecular clouds. The full GPIPS data set will contain almost 6 million stars, wit...
Wide-Field Infrared Survey Explorer (WISE) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The Wide-Field Infrared Survey Explorer (WISE) maps the entire sky at mid-infrared wavelengths--3.4, 4.6, 12, and 22 microns—corresponding to an angular resolution of 6.1, 6.4, 6.5, and 12”. WISE achieves a 5σ point source sensitivity of better than 0.08, 0.11, 1, and 6 mJy for bands 1-4, which corresponds to Vega magnitudes of 16.5, 15.5, 11.2, an...
MIPS Galactic Plane Survey (MIPSGAL) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The MIPSGAL survey covers 278 sq. deg of the inner Galactic Plane at 24 μm (6” resolution) and 70 μm (18” resolution). It is meant to act as a longer wavelength component to the Spitzer-GLIMPSE Survey of the Galactic plane. Its two main science goals are to 1) identify high mass protostars and 2) probe properties of interstellar dust in the inner g...
Herschel Infrared Galactic plane survey (Hi-GAL) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The Herschel Infrared Galactic plane survey (Hi-GAL) is an unbiased photometric survey covering |b| <= 1.0°, 68 > l > -70° in five passbands between 70 and 500 μm. The nominal beam sizes range from 5-35". Its key science goals include understanding the distribution of the ISM temperature, the formation of molecular clouds, the timeline of high-mass...
James Clerk Maxwell Telescope Plane Survey (JPS) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The James Clerk Maxwell Telescope Plane Survey (JPS) maps |b| ≤ 1.0° and 7° ≲ l ≲ 63° in 850 μm continuum emission with SCUBA-2. Its typical resolution is between 8 and 15 arcsec. As of September 2015, the observations are about 40% complete. The link to the homepage of the JPS survey can be found here.
APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) Dataverse(Harvard-Smithsonian Center for Astrophysics)
Sep 5, 2016
The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) maps 400 sq. deg. of the inner galaxy (|l| < 60º, |b| < 1.5º) at 870 μm with a uniform sensitivity of a few solar masses at a distance of 1 kpc. It has a spatial resolution of 19”. Its main sciences goals are to understand the early stages of high mass star formation, through a comprehen...
