Mapping Circumgalactic Medium Observations to Theory Using Machine Learning

Sarah Appleby, Romeel Davé, Daniele Sorini +2

We present a random forest framework for predicting circumgalactic medium (CGM) physical conditions from quasar absorption line observables, trained on a sample of Voigt profile-fi…

The Physical Nature of Circumgalactic Medium Absorbers in Simba

Sarah Appleby, Romeel Davé, Daniele Sorini +2

We study the nature of the low-redshift CGM in the Simba cosmological simulations as traced by ultraviolet absorption lines around galaxies in bins of stellar mass ($M_\star>10^{10…

How baryons affect halos and large-scale structure: a unified picture from the Simba simulation

Daniele Sorini, Romeel Dave, Weiguang Cui +1

Using the state-of-the-art suite of hydrodynamic simulations Simba, as well as its dark-matter-only counterpart, we study the impact of the presence of baryons and of different ste…

The Low Redshift Circumgalactic Medium in Simba

Sarah Appleby, Romeel Davé, Daniele Sorini +2

We examine the properties of the low-redshift circumgalactic medium (CGM) around star-forming and quenched galaxies in the Simba cosmological hydrodynamic simulations, focusing on…

Identification of MHD compressible modes in interstellar plasma with synchrotron emission polarization

Alexey Chepurnov, Reinaldo Santos de Lima, Sarah Appleby

We provide a procedure for identification of dominating compressible and Alfvenic MHD modes or isotropic turbulence in synchrotron emission polarization maps of Galactic objects. T…

The impact of quenching on galaxy profiles in the Simba simulation

Sarah Appleby, Romeel Davé, Katarina Kraljic +2

We study specific star formation rate (sSFR) and gas profiles of star forming and green valley galaxies in the Simba cosmological hydrodynamic simulation. Star-forming galaxy half-…

Simba: Cosmological Simulations with Black Hole Growth and Feedback

Romeel Davé, Daniel Anglés-Alcázar, Desika Narayanan +3

We introduce the Simba simulations, the next generation of the Mufasa cosmological galaxy formation simulations run with Gizmo's meshless finite mass hydrodynamics. Simba includes…

Identification of plasma modes in Galactic turbulence with synchrotron polarization

Heshou Zhang, Alexey Chepurnov, Huirong Yan +3

Magneto-hydrodynamic (MHD) turbulence is ubiquitous and a fundamental ingredient underlying many astrophysical phenomena. The multiphase nature of interstellar medium and diversity…
