in this paper, we introduce a generalized birth process ( gbp ) which performs jumps of size $ 1, 2, \ dots, k $ whose rates depend on the state of the process at time $ t \ geq0 $. we derive a non - exploding condition for it. the system of differential equations that governs its state probabilities is obtained. in th... | arxiv:2110.01190 |
we describe v02 of igmspec, a database of publically available ultraviolet, optical, and near - infrared spectra that probe the intergalactic medium ( igm ). this database, a child of the specdb repository in the specdb github organization, comprises 403277 unique sources and 434686 spectra obtained with the world ' s ... | arxiv:1703.04695 |
we study properties of waves of frequencies above the photospheric acoustic cut - off of $ \ approx $ 5. 3 mhz, around four active regions, through spatial maps of their power estimated using data from helioseismic and magnetic imager ( hmi ) and atmospheric imaging assembly ( aia ) onboard solar dynamics observatory (... | arxiv:1206.5874 |
