Great Balls of FIRE

The second in our Great Balls of FIRE series, where we (me, Mike Grudić, Zach Hafen, and Astrid Lamberts study the formation and evolution of globular clusters in a realistic MHD galaxy simulation https://arxiv.org/abs/2203.16547. This is the second paper in a series. The first paper in the series (https://arxiv.org/abs/2203.05732) identified all the clusters that formed … Continue reading Great Balls of FIRE

NASA Grant to Support Our Group

Thrilled to say that our team has been awarded a NASA Astrophysics Theory Program (ATP) Grant (21-ATP21-0144) for the 2021 cycle! Split between CMU (PI: Rodriguez, Co-I: Trac) and Northwestern University (Co-Is: Fragione, Rasio), the 4 year, ~$750K grant is to study the dynamical evolution of nuclear star clusters, the largest and densest stellar clusters … Continue reading NASA Grant to Support Our Group

How to reduce the number of authors in your Zotero library

Are you a scientist with a bunch of Zotero entries that have 1000+ authors (*cough* the LIGO Scientific Collaboration *cough*)? Is your bibtex file huge, and does the Sync with Zotero option break whenever you try to load a bibtext file into Overleaf (with an unhelpful error message)? Then you should update your library to … Continue reading How to reduce the number of authors in your Zotero library

The Observed Rate of Binary Black Hole Merger can be Entirely Explained by Globular Clusters

In a new research note, we argue that it is now possible to explain the ENTIRE rate of merging binary black holes (BBHs) detected by LIGO with globular clusters. After the first detection (GW150914), the rate of BBH mergers that LIGO predicted was more than 200/Gpc^3/yr. Almost every formation channel predicted merger rates of around … Continue reading The Observed Rate of Binary Black Hole Merger can be Entirely Explained by Globular Clusters

Globular Clusters as Binary Black Hole Factories

So it's about time that I actually published something here, and this seems as good a topic as any.  As most of you probably know, LIGO, the Laser Interferometer Gravitational Wave Observatory, reported the detection of gravitational waves a couple of months ago!  Talk about a ridiculously exciting time to be doing what I do. … Continue reading Globular Clusters as Binary Black Hole Factories
