UVBLUE: a new high-resolution theoretical library of ultraviolet stellar spectra
L. H. Rodriguez-Merino, M. Chavez, E. Bertone +1
We present an extended ultraviolet-blue (850-4700 AA) library of theoretical stellar spectral energy distributions (SEDs) computed at high resolution, R= 50,000. The UVBLUE grid, a…
ATLAS vs. NextGen model atmospheres: a combined analysis of synthetic spectral energy distributions
E. Bertone, A. Buzzoni, M. Chavez +1
We carried out a critical appraisal of the two theoretical models, Kurucz' ATLAS9 and PHOENIX/NextGen, for stellar atmosphere synthesis. Our tests relied on the theoretical fit of…
The Red Radio Ring: a gravitationally lensed hyperluminous infrared radio galaxy at z=2.553 discovered through citizen science
J. E. Geach, A. More, A. Verma +49
We report the discovery of a gravitationally lensed hyperluminous infrared galaxy (L_IR~10^13 L_sun) with strong radio emission (L_1.4GHz~10^25 W/Hz) at z=2.553. The source was ide…
New insights in high-resolution spectroscopy: a wide theoretical library of R=500000 stellar spectra
E. Bertone, A. Buzzoni, L. H. Rodriguez-Merino +1
We present an extended theoretical library of over 800 synthetic stellar spectra, covering energy distribution in the optical range (lambda = 3500-7000 angstrom), at inverse resolu…
The role of the synchrotron component in the mid infrared spectrum of M 87
L. Buson, A. Bressan, P. Panuzzo +7
We study in detail the mid-infrared Spitzer-IRS spectrum of M 87 in the range 5 to 20 micron. Thanks to the high sensitivity of our Spitzer-IRS spectra we can disentangle the stell…
Early Science with the Large Millimeter Telescope: CO and [C II] Emission in the z=4.3 AzTEC J095942.9+022938 (COSMOS AzTEC-1)
Min S. Yun, I. Aretxaga, M. A. Gurwell +27
Measuring redshifted CO line emission is an unambiguous method for obtaining an accurate redshift and total cold gas content of optically faint, dusty starburst systems. Here, we r…
