Probing the Local Group Medium toward Markarian 421 with Chandra and the Far Ultraviolet Spectroscopic Explorer
halo intergalactic medium
2014/12/24
We report the detection of highly ionized gas at z ~ 0 seen in resonant UV and X-ray absorption lines toward the z = 0.03 blazar Mrk 421. A total of 13 X-ray and three UV lines were measured (or upper...
We report the spectroscopic confirmation of a submillimeter galaxy (SMG) at z = 4.547 with an estimated LIR = (0.5-2.0) × 1013 L. The spectra, mid-IR, and X-ray properties indicate the bolometric lumi...
One-micron spectroscopic studies of accretion and outflow in T Tauri stars
High resolution spectrum Classical T Taurus Stars Spectrum Air calibrator The stars
2014/12/9
High-resolution spectroscopy of classical T Tauri stars (CTTS) at one micron yields new insight into the interaction of accretion disks, outflowing gas, and the central stars. Eighty-one 0.95–1.12 μm ...

Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters I. Spectroscopic Data
2011/10/17
We used the DEIMOS spectrograph on the Keck II Telescope to obtain spectra of galaxies in the fields of five distant, rich galaxy clusters over the redshift range 0.5 < z < 0.9 in a search for luminou...
Spectroscopic Confirmation of Three z-Dropout Galaxies at z = 6.844 - 7.213: Lyman Alpha Demography of z ~ 7 Galaxies
Spectroscopic Confirmation z-Dropout Galaxies Lyman Alpha Demography z ~ 7 Galaxies
2011/10/10
We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in the SDF and GOODS-N. For 3 out of 11 objects, we detect an emission line at ~ 1um with a signal-to-noise rati...
Spectroscopic confirmation of z~7 LBGs: probing the earliest galaxies and the epoch of reionization
Spectroscopic confirmation earliest galaxies epoch reionization
2011/9/29
We present the final results from our ultra-deep spectroscopic campaign with FORS2 at the ESO/VLT for the confirmation of z~7 "z--band dropout" candidates selected from our VLT/Hawk-I imaging survey o...
Spectra of globular clusters in the Sombrero galaxy: evidence for spectroscopic metallicity bimodality
globular clusters: general galaxies: individual: Sombrero (M104: NGC4594) galaxies: star clusters
2011/9/28
We present a large sample of over 200 integrated-light spectra of confirmed globular clusters (GCs) associated with the Sombrero (M104) galaxy taken with the DEIMOS instrument on the Keck telescope. A...
