Quasi-simultaneous two band optical variability of the blazars 1ES 1959+650 and 1ES 2344+514
Haritma Gaur, Alok C. Gupta, A. Strigachev +8
We report the results of quasi-simultaneous two filter optical monitoring of two high-energy peaked blazars, 1ES 1959+650 and 1ES 2344+514, to search for microvariability and short…
Observatons of NGC 3077 Galaxy in Narrow Band [SII] and H_alpha Filters
M. Andjelic, K. Stavrev, B. Arbutina +2
We present observations of the HI tidal arm near dwarf galaxy NGC 3077 (member of the M81 galaxy group) in narrow band [SII] and H_alpha filters. Observations were carried out in M…
Spectra probing the number ratio of C- to M-type AGB stars in the NGC 6822 galaxy
Nikolay Kacharov, Marina Rejkuba, Maria-Rosa L. Cioni
Aims: We calibrate spectroscopically the C- versus (vs.) M-type asymptotic giant branch (AGB) star selection made using near-IR photometry, and investigate the spatial distribution…
Spectral Energy Distribution variation in BL Lacs and FSRQs
Bindu Rani, Alok C. Gupta, R. Bachev +9
We present the results of our study of spectral energy distributions (SEDs) of a sample of ten low- to intermediate-synchrotron-peaked blazars. We investigate some of the physical…
