IAU symposium 356 – Nuclear Activity in Galaxies Across Cosmic Time

This is the second announcement of the IAU symposium 356 on ‘Nuclear
Activity in Galaxies Across Cosmic Time’, to be held in Addis Ababa in
Ethiopia, from October 7 – 11, 2019. We apologise if you received this
information multiple times. Please take a note that deadline for
abstract submission is next Tuesday 30 of April.

This is only the third symposium to be held in Africa in the past 100
years of the IAU. Currently many African countries are putting huge
efforts in developing astronomy and space science for their long-term
socioeconomic benefits. Therefore, beside revising the physics behind
AGN, another important aim of the IAU 356 symposium is to contribute to
the development of astronomy in Ethiopia and Africa in general. Please
help us in achieving these aims, by coming to the meeting and sharing
your knowledge and experience, and by
forwarding this information in your research centres and within your
colleagues.

Many thanks in advance, and we are looking forward to host you in
Ethiopia.

Best wishes, and have a nice day,

Mirjana Mpovic
on behalf of organisers

SUMMARISED RATIONALE:
With this conference we would like to achieve two main goals. First, we
want to provide a general overview of recent findings and progress in
observations, simulations, and theory of AGN from the local universe up
to high redshifts. This includes the following questions:

1. What have we learnt from AGN multiwavelength studies and what can we
expect from future instruments such as eROSITA, JWST, Euclid, CTA, SKA,
E-ELT, Athena, etc.?

2. What is the current status of the unification model of AGN? What are
the components distinguishing type-1 and type-2 AGN?

3. What do we know about AGN host galaxies? What is the effect of AGN on
their host galaxy and how important is AGN feedback compared with
stellar feedback in the context of preserving (or not) SMBH scaling
relationships at low and high redshift?

4. What is the status of AGN theory and numerical simulations regarding
AGN triggering, including mergers and secular processes, AGN disks, AGN
outflows and the shutting off of AGN activity?

5. How well we understand the origin of jets and their impact on galaxy
evolution? What evidences do we have for AGN positive and negative
feedback across cosmic time? In what kind of environments AGN reside?

6. How precisely can we measure BH mass at different redshifts?

7. What are the properties of highest-redshift AGN? What do we know
about AGN evolution?
Secondly, we aim at strengthening the development of science in Ethiopia
and Africa and opening new space for collaborations between Africa and
other parts of the globe for the benefit of all.
