What are the OPC Categories?

What are the OPC Categories?

The Observing Programmes Committee (OPC) is the body in charge of reviewing, evaluating on scientific merit, and ranking the proposals submitted in response to a call for the use of ESO observing facilities of the La Silla Paranal Observatory and thereby advise the Director General on the distribution of observing time, taking account of ESO's scientific policy. The OPC is assisted in its task by Expert Panels covering specific scientific areas, called Categories. The OPC Categories are listed below. When submitting a proposal, the Principal Investigator and Co-investigators are requested to choose the appropriate OPC category for their proposal.

More information can be found here.

As of P110, Distributed Peer Review (DPR) has been introduced at ESO to decrease the load on the OPC and Panels.


A - COSMOLOGY AND THE INTERGALACTIC MEDIUM

A1

Galaxies in their environment (e.g. galaxies in groups and clusters, merging galaxies, galaxy interactions, ram-pressure stripping of galaxies in groups and clusters)

A2

Global properties of galaxy groups, clusters and proto-structures including the intracluster medium

A3

Dark matter and gravitational lensing

A4

Intergalactic medium, circumgalactic medium and intervening absorption systems (e.g. Lyman alpha clouds, damped Lyman alpha systems and associated galaxies)

A5

Discovery surveys and the statistical study of galaxy properties (e.g. spectroscopic and redshift surveys, identifications, large scale structure, galaxy luminosity function and mass function, surveys for active galactic nuclei)

A6

Reionization and cosmic dawn (probes of reionization, galaxies in the epoch of
reionization)

A7

Cosmological parameters (e.g. distance scale, dark energy, fundamental physics).


B - GALAXIES  

B1

The Milky way and local group galaxies

B2

Resolved and unresolved stellar populations in galaxies beyond the Local Group (e.g. stellar metallicity, star formation histories)

B3

Galaxy structure, dynamics and kinematics (e.g. bulges, disks, morphology,
in/outflows, dark matter inside galaxies, stellar orbits)

B4

Dwarf galaxies, stellar clusters in galaxies and satellite galaxies

B5

Galactic centre, galaxy nuclei and supermassive black holes

B6

Physics of Active Galactic Nuclei
