A UV to IR Portrait of the Milky Way

Cat Fielder, University of Pittsburgh

Understanding where the Milky Way fits in amongst the broader galaxy population is critical for bridging the gap between detailed studies that are within our own galaxy (via SDSS-IV APOGEE and SDSS V Milky Way Mapper for example) and the observed trends in external galaxies (via MaNGA for example). Our previous work on using Milky Way analog galaxies in SDSS to predict the Milky Way’s optical colors used just two properties to define analogs (stellar mass and star formation rate), but there are other properties useful for selecting analogs (e.g., disk scale length or axis ratio). However, the number of analog galaxies rapidly approaches zero as more selection properties are included. To address this issue, I present a new method using Gaussian Process Regression that allows for consideration of up to six parameters simultaneously while still giving robust predictions of broad-band fluxes. I will present results using these improved methods on the color and luminosity of the Milky Way, and will demonstrate how the inferred properties of the Milky Way compare to transitional/green valley populations. I find that the Milky Way is still experiencing  enough star formation to appear more blue than the green valley in both the ultraviolet and infrared.

MHD waves in the solar atmosphere

Erwin Verwichte, University of Warwick

The Sun is the our nearest star and the only one that directly affects the Earth on a daily basis. Its light and heat keeps our planet habitable, but its space weather activity challenges our technology and journey into deep space. We study the solar atmosphere to understand the physical processes that underlie this activity, and that manifests itself through flares, coronal mass ejections, equatorial coronal holes,…

But we also study the Sun because it is only star we can examine in exquisite spatially resolved detail and reveal the stellar processes responsible for the activity cycle, the transport of mass and heat through the chromosphere, heat deposition in the higher atmosphere and the acceleration of the solar wind. We use plasma physics and magnetohydrodynamics (MHD) The magnetically dominated corona also shares much of the physics that is found in magnetically confined fusion experiments.

Magnetohydrodynamic (MHD) waves are prevalent throughout the solar atmosphere and play pivotal roles in the aforementioned processes. I will introduce how the various types of MHD waves manifest themselves at the Sun, illustrated by examples from modern ground-based and space-born observations. In particular, I will focus on studies of waves in thermally active plasmas, both at hot and cool temperatures, that are directly linked to flaring.
I will show how waves can provide insight into magnetic reconnection underlying flares as well as into thermal instabilities that are part of the atmospheric mass cycle.
