<p>Hi all,</p>
<p><br>
</p>
<p>For the first PASS talk of the quarter, Prady will talk about
his work on satellite galaxies, and intersections of analytical
models and numerical simulations. Please join us on <b>October
15th (Monday)</b> at <b>noon</b> (from 12:00 pm to 1:00 pm)
in the <b>Conference Room</b> (PHYS 3051).</p>

<div align="center">Current cosmological simulations lack the
resolution to make reliable predictions for faint and
ultra-faint dwarf satellites, which will become a crucial test
of the LCDM model in the upcoming era of the Vera Rubin
Observatory. To this end, we implement a semi-analytical model
fitted to high-resolution controlled simulations to complement
the predictions of the TNG50 cosmological numerical simulations.
We focus on 3 clusters with virial masses ~1e14 Msun, comparable
to Virgo and Fornax, and characterize their satellite population
from ultrafaint dwarfs to massive elliptical galaxies. We find
that under the assumption of cuspy dark matter halos such as NFW
profiles, the majority of all satellite galaxies survive within
cluster environments, expecting 10-100 thousand luminous
satellites within the virial radius of such clusters. This is
contrary to the results directly from the simulation where
satellites get merged artificially due to poor numerical
resolution. We characterize the radial distribution of
satellites.<b><br>

<div>Hello Physics and Astronomy students (and PostDocs),</div>
<div><br>
</div>
<div>Just like last year, a group of us is organizing the
Physics and Astronomy Student Seminars (PASS) for this year.
It is a weekly student-run seminar series by members of the
Physics and Astronomy department for their peers. PASS is a
fantastic opportunity for you to share your research, learn
from your peers, and practice your presentation skills in a
stress-free environment. Everyone is welcome, both to attend
and to sign up as speakers. <br>
</div>
<div><br>
</div>
<div>We're in the process of scheduling these seminars at a
time that works best for most.<b> We would greatly
appreciate your help in determining this by filling out
the <a href="https://www.when2meet.com/?26869502-61cQX"
moz-do-not-send="true">when2meet</a>.</b> We're looking
to kick things off next week, so please keep that in mind
when you're filling it out.<br>
