Detecting Obscured AGN in the Distant Universe with Spitzer
J. L. Donley, G. H. Rieke, P. G. Perez-Gonzalez +2
We present the results of a Spitzer search for obscured AGN in the Chandra Deep Field-North, using both radio-excess and mid-infrared power-law selection. AGN selected via the form…
Star Formation Rate estimators: [OII]3727 vs. Halpha for local star-forming galaxies
A. Aragon-Salamanca, A. Alonso-Herrero, J. Gallego +4
The [OII]3727 emission line is frequently used as an indicator of the star formation rate (SFR) despite its complex dependence on metallicity and excitation conditions. We have ana…
12CO mapping of the low-metallicity BCD galaxy Mrk86
A. Gil de Paz, S. A. Silich, B. F. Madore +3
We have mapped the 12CO J=1-0 and J=2-1 line emission in Mrk86, one of the most metal-deficient Blue Compact Dwarf galaxies so far detected in 12CO. The 12CO emission is distribute…
MUSICOS 1998: Optical and X-rays Observations of Flares on the RS CVn Binary HR 1099
D. Garcia-Alvarez, B. H. Foing, D. Montes +2
We present simultaneous and continuous observations of H_alpha, H_beta, NaI D_1, D_2 and HeI D_3 lines of the chromospherically active binary HR 1099. We have observed HR 1099 for…
MUSICOS 1998: Observations of Rotational Modulation and Flares on the RS CVn Binary HR 1099
D. Garcia-Alvarez, B. H. Foing, D. Montes +2
We present simultaneous and continuous observations of H_alpha, H_beta, NaI D_1, D_2, HeI D_3 and CaII H & K lines of the chromospherically active binary HR 1099. We have observed…
Chromospheric activity of the double-lined spectroscopic binary BF Lyn
D. Montes, R. Lachaume, M. J. Fernandez-Figueroa
We present simultaneous spectroscopic observations taken during four observing runs (1996 to 1999) of H_alpha, H_beta, H_epsilon, Ca II H & K, and Ca II IRT lines of the chromosphe…
