The SDSS-III Apache Point Observatory Galactic Evolution Experiment (APOGEE) will obtain high resolution (R 22,500) and high S/N ( 100 per pixel) H-band spectra of 100,000 giant stars in the Milky Way disk, bulge and halo to study the chemical and kinematical evolution of the Milky Way Galaxy. APOGEE will be able to probe deep into regions of our

The Apache Point Observatory Galactic Evolution Experiment (APOGEE), part of the Sloan Digital Sky Survey III, is exploring the stellar populations of the Milky Way using the Sloan 2.5-m telescope linked to a high resolution (R 22,500), near-infrared (1.51-1.68 microns) spectrograph with 300 optical fibers. For about 100,000, predominantly red

The stellar content of the bulge of the Galaxy is not well characterized yet, in part due to the high extinction and, therefore, limited access at optical wavelengths. The SDSS-III Apache Point Observatory Galaxy Evolution Experiment (APOGEE) is an on-going near-infrared survey acquiring very high quality spectra (S/N > 100 per pixel, R 22,500) of

We present pitch angle measurements of a nearly complete sample of nearby spiral galaxies. Using these results along with the relationship between supermassive black hole mass and the pitch angle of the host galaxy's spiral arms, we have determined the black hole mass function for local spiral galaxies. The pitch angle measurements were obtained by

We investigate the nature of the broad-band emission associated with the low-power radio hotspots 3C 105 South and 3C 445 South. Both hotspot regions are resolved in multiple radio/optical components. High-sensitivity radio Very Large Array, near-infrared/optical Very Large Telescope and Hubble Space Telescope (HST) and X-ray Chandra data have been

We present an intensive radio and X-ray monitoring campaign on the 2009 outburst of the Galactic black hole candidate X-ray binary H1743-322. With the high angular resolution of the Very Long Baseline Array, we resolve the jet ejection event and measure the proper motions of the jet ejecta relative to the position of the compact core jets detected
