چکیده
4C+28.07 is a $\gamma$-ray Flat Spectrum Radio Quasar (FSRQ) type source. It often monitored at different frequencies, though long-term multi-wavelength data of this source have not been modelled in detail before. We analyzed $\sim 12$ years (Aug, 2008 - May, 2020) Fermi-LAT with binning 10 days time scale and observed three distinctive flaring states. Each state consists phases activity, namely, pre-flare, flare \& post-flare regions. spectral analysis these activity has performed the best fit model for its spectra found to be Log-parabola model. also studied correlation simultaneous light curves optical radio counterparts states report DCF 95\% significance level. A large delay between gamma-ray two flares, indicating zones emission. fitted two-zone leptonic In our model, maximum required power jet 9.64 $\times$ 10$^{46}$ erg sec$^{-1}$, which lower than Eddington luminosity $2.29\times 10^{47}$ sec$^{-1}$.

A Multi - Wavelength Infrared Study of NGC 891
We present a multi-wavlength infrared study of the nearby, edge-on, spiral galaxy NGC 891. We have examined 20 independent, spatially resolved IR images of this galaxy, 14 of which are newly reduced and/or previously unpublished images. These images span a wavelength regime from λ 1.2 μm in which the emission is dominated by cool stars, through the MIR, in which emission is dominated by PAHs, t...
متن کاملMulti-Wavelength Laser Opacity Study of a Hybrid Rocket Plume
An instrumentation system was developed to measure the opacity of a hybrid rocket plume as a function of optical wavelength. The source consisted of collineated beams from two lasers, providing seven wavelengths in a single probe beam. Detection was accomplished with a spectrograph equipped with a photodiode array. Previous work with a two-wavelength system demonstrated the ability to follow th...
متن کاملMulti-Wavelength Fiber Lasers
Nowadays, multiwavelength lasers are of great interest for telecommunications and sensors multiplexing. These lasers also have a great potential in the fiber-optic test and measurement of WDM components. The requirements for such optical sources are: a high number of channels over large wavelength span, moderate output powers (of the order of 100μW per channel) with good optical signal to noise...
