PCOS Science Goals

Understand the formation and growth of massive black holes and their role in the evolution of galaxies

The massive black holes (~109 solar masses) ubiquitous in the Universe today are thought to stem from seed black holes formed early in the Reionization era. The origin of these seeds is uncertain. They may have formed from either large stellar mass black holes (~100 solar masses) left over from the first stars or intermediate mass black holes (~104–5 solar masses) formed directly by the collapse of supermassive gas clouds. Whether supermassive black holes grow through mergers or accretion, their host galaxies appear to have co-evolved with them. A strong correlation has become evident between the properties and evolution of galaxies and the growth of their central supermassive black holes. The energetic processes around SMBHs result in huge radiative andmechanical outputs that could potentially have a profound effect on their larger scale environment in galaxies, clusters and the intergalactic medium. But quantitative descriptions of the interaction between massive black hole growth and galaxy growth are lacking. Understanding the formation of galaxies, and their subsequent evolution, will be coupled to intensive study of the evolution of supermassive black holes.

To attend in person at the University of Colorado campus, please RSVP here. The live stream will be available here. For further details, please see the colloquium invitation. »  Details
17 May 2019
Following up on a Nov 2018 mission PI diversity workshop, the NASA Science Mission Directorate (SMD) is planning a number of exciting opportunities open to community participation, including a new website for potential PIs, pre-review mission panels to ensure diversity and reduce conflicts of interest, research proposal writing workshops at conferences and for PIs developing their first proposal, career development positions, and a presentation by SMD Associate Administrator Thomas H. Zurbuchen on proposal statistical analysis. Please see the Associate Administrator's full update here.
16 May 2019
June 1 2019 is the deadline for filling and submitting the technology gap submission form. We encourage members of the community to identify such gaps between today's state-of-the-art and what will be needed for missions identified by the 2010 Decadal Survey, the 2018 Astrophysics Implementation Plan, and/or the 30-year Astrophysics Road Map. Please see the Astrophysics Division Technologists letter for more details, including how to submit a gap.
25 March 2019
NASA HQ Astrophysics Division has created a task force to assess NASA's role in strategic optimization of Gravitational Wave Electromagnetic Counterpart (GW-EM) astrophysics. See the Terms of Reference for more details.
1 February 2019
Dr Terri Brandt confirmed as PCOS Chief Scientist.
