Astrophysical jets are produced by a wealth of objects, from stars being born, to stars collapsing and dying, to various flavours of dead stars. The collimated outflows in each scenario are launched due to the process of accretion, whether it be onto a young stellar object, from a magnetized hot flow around a black hole, or during a stellar collapse and the production of a gamma-ray burst. After the birth of jets, they accelerate, escape the gravitational field of their birthplace, before injecting energy into and drive chemistry in their surroundings. In planet forming protostellar disks the outflowing material might even affect planet migration. Thus there are a multitude of processes taking place at various stages and on different scales. Many of the identified processes are important in both jets from compact objects, protostellar sources and other astrophysical jets. Some efforts have been taken to bridge the various communities to maximize the synergy. Therefore we aim to continue this with a meeting where astronomical researchers from any community will present their latest findings on astrophysical jets and outflows.
We aim to discuss the latest advances, theoretical and observational, and future prospects in understanding the role of astrophysical jets and outflows in all types of sources, bringing together the different jet communities, from protostars, to accreting black holes
(supermassive, stellar-mass and intermediate-mass), evolved stars, neutron stars, white
dwarfs, gamma-ray bursts (GRBs), tidal disruption events (TDEs) and ultraluminous X-ray
sources (ULXs). In terms of feedback, black hole jets energise large-scale synchrotron
lobes, and protostellar jets/outflows mix disk-processed species and grains into the surrounding cloud and also act as regulators of star masses and the global star formation timescales. Common physics exists across the power scale of relativistic jets, starting with the Fundamental Plane of black hole activity, to more recent advancements linking jets in black holes to those in GRBs, CVs, YSOs, and TDEs. Jets and outflows are regulators of feedback - in terms of star formation (especially in the case of protostellar jets) and of galaxy growth in the early Universe (AGN).
Clearly a tight connection between theory and observations is required in order to bridge the large span of physical scales involved (size, density, temperature), as well as a coupling with the chemistry. Furthermore, there are several cases where the different communities can work together and share advances to increase the understanding of jets and outflows. We believe that bringing together experts on theory and observations to discuss these topics and questions will be beneficial for the general understanding of the importance and impact of astrophysical jets and outflows. The structure of the meeting will allow experts from different fields to better understand outflow physics under different conditions and to encourage new thinking in each field and collaborations between fields.
Therefore we invite you to submit your contributed talk to participate in this opportunity to bridge several astronomical communities.
The symposium will run over 6 blocks of 1.5 hours each, where the talks will organised in terms of topic and focus on commonalities (and differences) to further discussion and synergy between the communities.
