Conference Postponed.

Due to the rapidly evolving Covid-19 situation worldwide, and due to new immigration rules of Nepal itself (including a 2 week self-quarantine for all foreigners entering the country), our conference has been postponed by one year.
The new conference date is

April 18-23, 2021

All 2020 participants will be re-contacted later this year.


Growing Black Holes: Accretion and mergers, 19-24 April 2020, is the seventh in a series of astrophysical conferences held in Kathmandu (Nepal). The meeting will focus on various aspects on accretion onto black holes, mergers of compact objects forming black holes, and jets formed in those systems. Emission of those systems/events in electromagnetic radiation, gravitational waves and neutrinos will be also addressed.

This conference will be in memory of Sergio Colafrancesco.
Sergio has been among the conference organizers for most of the previous conference editions. He was an internationally recognized scientist, expert in cosmology and astrophysics and a Nepal lover.

Main Topics

    • Black holes of all masses
    • Compact object mergers at all scales (stellar mass & supermassive), EM and GW signatures
    • Physics of accretion, disc winds and jets – Galactic systems, IMBHs, and AGN
    • Stellar tidal disruption events (TDEs)
    • Large-scale feedback: jets and outflows
    • Galaxy – BH scaling relations
    • Collapsars: black hole formation and GRBs
    • Multimessenger astrophysics
    • Mission Highlights and upcoming missions
