Optical design and prototype of a high resolution near IR spectrograph for astronomy.
(2019)
The search for extraterrestrial planets is an exciting current field of research. One of the
most efficient ways to detect exoplanets is through the measurement of the Radial Velocity
(RV) detection of Doppler shifts of ...
A TALE OF THREE GALAXIES: DECIPHERING THE INFRARED EMISSION OF THE SPECTROSCOPICALLY ANOMALOUS GALAXIES IRAS F10398+1455, IRAS F21013-0739, AND SDSS J0808+3948
(IOP PUBLISHING LTD, 2015)
The Spitzer/Infrared Spectrograph spectra of three spectroscopically anomalous galaxies (IRAS F10398+ 1455, IRAS F21013-0739, and SDSS J0808+3948) are modeled in terms of a mixture of warm and cold silicate dust, and warm ...
X-ray Constraints on the Active Galactic Nuclei Properties in Spitzer-Infrared Spectrograph Identified z ~ 2 Ultraluminous Infrared Galaxies
(2010)
We report Chandra X-ray constraints for 20 of the 52 high-redshift ultraluminous infrared galaxies (ULIRGs) identified in the Spitzer Extragalactic First Look Survey with f ν(24 μm)>0.9 mJy, log ({ν f_{ν}(24 μm)\over ν ...
TARdYS: Design and prototype of an exoplanet hunter for TAO using a R6 Echelle grating
(2019)
One limitation in characterizing exoplanet candidates is the availability of infrared, high-resolution spectrographs. An important factor in the scarcity of high precision IR spectrographs is the high cost of these ...
High spatial resolution spectroscopy of W51IRS 2E and IRS 2W: Two very massive young stars in early formation stages
(IOP PUBLISHING LTD, 2008)
We present K-band spectra of the near infrared counterparts to IRS 2E and IRS 2W which is associated with the ultracompact H II region W51d, both of them embedded sources in the Galactic compact H II region W51 IRS 2. The ...
Unveiling the nature of IGR J16493-4348 with IR spectroscopy
(2010)
The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering a large number of new hard X-ray sources, many of them being HMXBs. The identification and spectral characterization of their optical/infrared ...
Optical Spectroscopy of X-Ray Sources in the Extended Chandra Deep Field South
(2009)
We present the first results of our optical spectroscopy program aimed to provide redshifts and identifications for the X-ray sources in the Extended Chandra Deep Field South. A total of 339 sources were targeted using the ...
Unveiling the nature of six HMXBs through IR spectroscopy
(2008)
The International Gamma-Ray Astrophyiscs Laboratory (INTEGRAL) is discovering a large number of new hard X-ray sources, many of them being HMXBs. The identification and spectral characterization of their optical/infrared ...
