Maret Einasto
Tartu Observatory at Tartu University

What is your name, affiliation, academic position, and job title?
My name is Maret Einasto, I am affiliated to the Tartu Observatory at Tartu University, Estonia, as an Associate Professor.

What is your field of research and/or what project are you involved in?
Large-scale structure of the Universe

What are your research plans?
I want to study the properties and evolution of galaxies in the largest structures of the cosmic web – superclusters and voids, and the origin of the characteristic scales in their distribution.

How does CosmoVerse fit within those plans?
One example: the origin and nature of characteristic scales in the superclusters distribution have even not studied yet, thus we do not know whether they are in tension with LCDM.

What are the most exciting open questions in your research area?
The formation and coevolution of galaxies in the cosmic web

What advances or new results are you excited about or looking forward to?
Understanding galaxy formation in the lowest density regions of the cosmic web, in cosmic voids

What is your view on cosmic tensions? How does your work connect with this open question in the community?
My work in related to tensions in S8 parameter and biasing. Moreover, we even do not know whether the properties of the largest structures (superclusters and supercluster planes, shell-like structures in the superclusters distribution, characteristic scales in the supercluster distribution (ca 120 h(-1) Mpc; I do not refer to BAO scale here), and others) are in agreement with LCDM.

What role do you think a community network like CosmoVerse can play in developing theoretical astroparticle physics and cosmology?
Connecting people

If you were not a scientist, what do you think you would be doing?
I would be a photographer.

In your view, what’s the most important challenge that humanity faces currently?
Environment; survival of nature and humanity
