Broad Band Photometric Reverberation Mapping of NGC 4395

open access: yes, 2012
We present results of broad band photometric reverberation mapping (RM) to measure the radius of the broad line region, and subsequently the black hole mass (M$_{\rm BH}$), in the nearby, low luminosity active galactic nuclei (AGN) NGC 4395.

Solving geocryology problems based on generalized Fourier theory for temperature waves in half-space

open access: yesФизика волновых процессов и радиотехнические системы
Background. Currently, in geocryology, to predict seasonal changes in the state of frozen rocks and soils, Fourier formulas obtained earlier are widely used, modeling temperature fluctuations in the surface layer of the earth’s crust caused by annual ...

Experimental determination of time lag and decrement factor

open access: yesCase Studies in Construction Materials, 2019
Buildings consume about 40% of the primary energy in the world. This means that buildings are responsible for the majority of greenhouse gas emissions. It’s time to reduce this energy consumption to limit the environmental impact of buildings. The use of

Lag-luminosity relation in gamma-ray burst X-ray flares: a direct link to the prompt emission

open access: yes, 2010
The temporal and spectral analysis of 9 bright X-ray flares out of a sample of 113 flares observed by Swift reveals that the flare phenomenology is strictly analogous to the prompt gamma-ray emission: high energy flare profiles rise faster, decay faster ...
