About me
I am Bahar Bidaran, a professional researcher in astrophysics. I am currently working as a postdoc researcher at the University of Granada, Spain and as part of the CAVITY international collaboration. My work mainly focuses on low-mass galaxies (aka dwarf galaxies) in different large-scale structures (such as voids, filaments, and clusters). I am an observational astronomer, mostly working with optical data from observatories like VLT in Chile and CALAR ALTO in Spain.
In addition to my research, I enjoy painting, reading books, and cooking.
My research
Evolution of dwarf galaxies in
high density environments
Low-mass galaxies (AKA dwarfs) are one of the most abundant types of galaxies in the Universe. In high-density environments, such as galaxy clusters and groups, they are frequently found to be red, quenched (with low star formation rates, if any), and pressure-supported. Environment of their present-day host halos is believed to play a prominent role in transforming late-type dwarfs to quiescent ones through mechanisms such as ram pressure stropping, tidal interaction and starvation. But how about pre-processing in their previous host halo(s)? This can be the environment of a less massive galaxy group or a filament. So my question is: How relevant is pre-processing in shaping present-day properties of dwarf galaxies in massive clusters and groups?
Evolution of dwarf galaxies in
pristine environments
What did the progenitors of present-day early-type dwarf galaxies look like? Do they have a similar origin to early-type dwarfs? Can we trace the footprints of their progenitors in their present-day observed properties? To answer these questions, we must carefully investigate dwarf galaxies in pristine environments. Currently, I am focused on the low-mass Void galaxies, looking more closely at their physical properties to understand how such a pristine environment could have affected their evolution.
