Interstellar Extinction in the Vicinity of Galactic Center Thermal Radio Emission Regions
نویسندگان
چکیده
Broad band J, H and K 0 and spectral Br 2.166 m images have been obtained in four areas surrounding regions of thermal radio emission. Localized variations in the extinction are examined by means of color and comparison of the observed Br ux with the Br emission predicted from radio continuum data. Results show few spatial variations and little correlation with the position of the radio emission features.

Interstellar Extinction in the Vicinity of the Galactic Center
We present J (1.2 km), H (1.6 km), K@ (2.11 km), and Brc (2.166 km) images from four large regions within the central 40 pc of the Galaxy. Localized variations in the extinction, as determined by observations of the stellar population, are examined using the median H[K@ color as a function of position within each region. As the value of the derived extinction from the stars is dependent upon th...
متن کاملChandra Observations of the Galactic Center and Nearby Edge-on Galaxies
I review our recent Chandra surveys of the center region of the Milky Way and other nearby edge-on galaxies. Our Galactic center survey, consisting of 30 overlapping pointings, provides an unprecedented high-resolution, broadband X-ray view of a 0.8x2 square degree swath along the Galactic plane. This X-ray panorama allows a separation of the discrete source and diffuse X-ray components. Our pr...
متن کاملMagnetic structure of our Galaxy: A review of observations
The magnetic structure in the Galactic disk, the Galactic center and the Galactic halo can be delineated more clearly than ever before. In the Galactic disk, the magnetic structure has been revealed by starlight polarization within 2 or 3 kpc of the Solar vicinity, by the distribution of the Zeeman splitting of OH masers in two or three nearby spiral arms, and by pulsar dispersion measures and ...

Nonthermal radio emission in the galactic center reveals a number of vertical structures across the galactic plane, which are attributed to poloidal magnetic field and/or energetic outflow. Thermal radio emission comprises star forming regions distributed in a thin, dense thermal gas disk. The thermal region is associated with dense molecular gas disk, in which the majority of gas is concentrat...
متن کاملThe interstellar medium of the Antennae Galaxies
To study the properties of the interstellar medium in the prototypical merging system of the Antennae galaxies (NGC 4038 and NGC 4039), we have obtained 12 CO (1–0), (2–1) and (3–2) line maps, as well as a map of the 870µm continuum emission. Our results are analysed in conjunction with data from X-ray to radio wavelengths. In order to distinguish between exact coincidence and merely close corr...
