The Circumgalactic Medium from the CAMELS Simulations: Forecasting Constraints on Feedback Processes from Future Sunyaev-Zeldovich Observations

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Emily Moser, Nicholas Battaglia, Daisuke Nagai, Erwin Lau, Luis Fernando Machado Poletti Valle | Summary: The cycle of baryons through the circumgalactic medium (CGM) is important to understand in the context of galaxy formation and evolution. In this study we forecast constraints on the feedback processes heating […]

Nature of novel moiré exciton states in WSe$_2$/WS$_2$ heterobilayers

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Mit H. Naik, Emma C. Regan, Zuocheng Zhang, Yang-hao Chan, Zhenglu Li | Summary: Moir’e patterns of transition metal dichalcogenide (TMD) heterobilayers have proven to be an ideal platform to host unusual correlated electronic phases, emerging magnetism, and correlated exciton physics. While the existence of novel moir’e […]

What drives galaxy quenching? A deep connection between galaxy kinematics and quenching in the local Universe

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Simcha Brownson, Asa F. L. Bluck, Roberto Maiolino, Gareth C. Jones, | Summary: We develop a 2D inclined rotating disc model, which we apply to the stellar velocity maps of 1862 galaxies taken from the MaNGA survey (SDSS public Data Release 15). We use a random forest […]

Finding Evidence for Inflation and the Origin of Galactic Magnetic Fields with CMB Surveys

Posted by klaurent Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Sayan Mandal, Neelima Sehgal, Toshiya Namikawa, , | Summary: The origin of the $mumathrm{G}$ magnetic fields observed in galaxies is unknown. One promising scenario is that magnetic fields generated during inflation, larger than 0.1 $mathrm{nG}$ on Mpc scales, were adiabatically compressed to $mumathrm{G}$ strengths in galaxies during […]

Cosmology with one galaxy?

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Francisco Villaescusa-Navarro, Jupiter Ding, Shy Genel, Stephanie Tonnesen, Valentina La Torre | Summary: Galaxies can be characterized by many internal properties such as stellar mass, gas metallicity, and star-formation rate. We quantify the amount of cosmological and astrophysical information that the internal properties of individual galaxies […]

Tidally Tilted Pulsators

Posted by klaurent MIT

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Gerald Handler, Rahul Jayaraman, Donald W. Kurtz, Jim Fuller, Saul A. Rappaport | Summary: The tidally tilted pulsators are a new type of oscillating star in close binary systems that have their pulsation axis in the orbital plane because of the tidal distortion caused by their […]

Percent-level constraints on baryonic feedback with spectral distortion measurements

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Leander Thiele, Digvijay Wadekar, J. Colin Hill, Nicholas Battaglia, Jens Chluba | Summary: High-significance measurements of the monopole thermal Sunyaev-Zel’dovich CMB spectral distortions have the potential to tightly constrain poorly understood baryonic feedback processes. The sky-averaged Compton-y distortion and its relativistic correction are measures of the total […]

A census of 163 large-scale (>=10 pc), velocity-coherent filaments in inner Galactic plane: physical properties, dense gas fraction, and association with spiral arms

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yifei Ge, Ke Wang, , , | Summary: The interstellar medium has a highly filamentary and hierarchical structure, which may play a significant role in star formation. A systematical study on the large-scale filaments towards their physical parameters, distribution, structures and kinematics will inform us of what […]

Augmenting astrophysical scaling relations with machine learning : application to reducing the SZ flux-mass scatter

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Digvijay Wadekar, Leander Thiele, Francisco Villaescusa-Navarro, J. Colin Hill, Miles Cranmer | Summary: Complex systems (stars, supernovae, galaxies, and clusters) often exhibit low scatter relations between observable properties (e.g., luminosity, velocity dispersion, oscillation period, temperature). These scaling relations can illuminate the underlying physics and can provide […]
