A New Model for the Milky Way Halo Dispersion Measure with the ENGAWA Simulations: Low DMs and Large Anisotropy
Scott Lucchini, Liam Connor, Samuel McCarty +1
Fast radio burst (FRB) dispersion measures (DMs) are powerful tracers of the low density universe, but interpretation is made difficult by the integrated nature of DM. In this pape…
The CGM with local universe FRBs: evidence of strong AGN feedback in a massive elliptical galaxy
Samuel McCarty, Liam Connor, Ralf M. Konietzka
Modern cosmology and galaxy formation rely on an understanding of how cosmic baryons are distributed, a significant portion of which exist in the diffuse gas confined to halos. Fas…
Ray-tracing Fast Radio Bursts Through IllustrisTNG: Cosmological Dispersion Measures from Redshift 0 to 5.5
Ralf M. Konietzka, Liam Connor, Vadim A. Semenov +3
The dispersion measures (DMs) of Fast Radio Bursts (FRBs) arise predominantly from free electrons in the large-scale structure of the Universe. The increasing number of FRB observa…
A gas-rich cosmic web revealed by the partitioning of the missing baryons
Liam Connor, Vikram Ravi, Kritti Sharma +17
Approximately half of the Universe's dark matter resides in collapsed halos; significantly less than half of the baryonic matter (protons and neutrons) remains confined to halos. A…
A Correlation Between FRB Dispersion Measure and Foreground Large-Scale Structure
Maryam Hussaini, Liam Connor, Ralf M. Konietzka +4
The distribution of baryons in the Universe remains a fundamental open question in astronomy, and the dispersion measure (DM) of Fast Radio Bursts (FRBs) serves as a valuable tool…
The Origin of the Cluster of Local Interstellar Clouds
Catherine Zucker, Seth Redfield, Sara Starecheski +2
The interstellar medium within of the Sun consists of a complex of fifteen diffuse, partially ionized clouds. Located within the Local Bubble, these clouds, k…
