MOLECULAR SPECTROSCOPY FOR COLLEGE STUDENTS
The molecular spectroscopy can be used for Introductory Astronomy
class using real data from published single dish telescope like APEX or IRAM, the public data from NASA and Interferometry observations at 1mm from ALMA (PI:Villicana- Pedraza).
The students learn the basics of the analysis of different kind of astronomical objects.
The observations show some tracers of dense gas and other tracers in galaxies such as Methanol and SiO, also, using the literature they can compare the abundances. In case of the planets the students can analize the spectra of some planets and compare the abundance in them.
In this talk we present the practice that we use in class with college students and some of the results from this activity in class
Multifrequency Study of the Blazar 3C 454.3
This work is devoted to multi-frequency studying of the blazar 3C 454.3. The study includes spectroscopic and photometric observations in the optical, IR, and gamma-ray bands. We investigate whether a correlation exists in the light curves at different wavelengths. We have carried out observations of the optical spectrum (from 4000 to 7000 Angstroms) between 2007 and 2009, and identified MgII [2800 Angstroms] and FeII emission line features. We have obtained optical magnitudes and color indices of the quasar and performed a correlation between the optical, IR, and gamma-ray light curves. We have found statistically significant correlations between the light curves at different wavelengths
