Direct Images of the Cosmic Web of Intergalactic and Circumgalactic Gas in the Distant Universe

Autor: Lanzetta, Kenneth M., Gromoll, Stefan, Shara, Michael M., Sololiuk, Oleksii, Valls-Gabaud, David, von der Linden, Anja, Walter, Frederick M., Webb, John K.

Most of the baryonic matter of the Universe resides in a highly-ionized gaseous intergalactic medium. This gas flows along dark-matter filaments toward galaxy superclusters, clusters, and groups until it pools around the galaxies into a circumgalacti

Cosmic shear, galaxy clustering, and the abundance of massive halos each probe the large-scale structure of the universe in complementary ways. We present cosmological constraints from the joint analysis of the three probes, building on the latest an

Millisecond Pulsars in Globular Clusters and Implications for the Galactic Center Gamma-Ray Excess

Autor: Amerio, Aurelio, Hooper, Dan, Linden, Tim

We study the gamma-ray emission from millisecond pulsars within the Milky Way's globular cluster system in order to measure the luminosity function of this source population. We find that these pulsars have a mean luminosity of $\langle L_{\gamma}\ra

Clusters, Clumps, Dust, & Gas (CCDG) in NGC1614: Bench-marking Cluster Demographics in Extreme Systems

Observations of young star clusters in a variety of galaxies have been used to constrain basic properties related to star-formation, such as the fraction of stars found in clusters (Gam) and the shape of the cluster mass function. However, the result
