Spectrophotometric reverberation mapping of Intermediate-mass black hole NGC 4395
Shivangi Pandey, Suvendu Rakshit, Krishan Chand +8
Understanding the origins of massive black hole seeds and their co-evolution with their host galaxy requires studying intermediate-mass black holes (IMBHs) and estimating their mas…
