Millisecond pulsars as anchors
MSPs provide a clean observational handle on neutron-star evolution. I use X-ray data to identify counterparts, compare cluster populations, and connect individual sources to their broader formation channels.
Research
Compact objects in rich environments
My research centers on X-ray observations of neutron stars and related systems, especially millisecond pulsars in globular clusters. I am most drawn to problems where source identification, population context, and multiwavelength evidence all have to work together.
Millisecond pulsars
Globular clusters
Magnetars
Galactic Center excess
Globular clusters as laboratories
The dense stellar cores of globular clusters efficiently create binaries and compact remnants, making them ideal environments for testing how interactions shape pulsar populations.
Related high-energy questions
Beyond classic MSP work, I am interested in the Galactic Center excess, magnetars, and long-period transients, especially where compact-object demographics may help resolve open questions.
Featured Environment
Omega Centauri and the cluster-core view
A recurring theme in my work is how to extract compact-object physics from crowded stellar fields without losing the population context that makes those environments valuable.
Millisecond pulsars are fast-spinning, highly magnetized neutron stars that were spun up through accretion in binary systems. In globular clusters, the high stellar density sharply increases the chances of building and reshaping those binaries through close encounters.
That is what makes clusters so compelling: they are not just source collections, but environments that actively influence the compact-object populations inside them. My X-ray studies of systems such as M5, M13, and Omega Centauri are all motivated by that connection.

Where the questions branch outward
Counterparts and population studies
I am interested both in individual X-ray counterparts and in the larger census they build toward. Recent work spans systems including M5, M13, Omega Centauri, Terzan 5, and Cas A.

Galactic Center excess
The GeV gamma-ray excess in the Galactic Center remains one of the most debated high-energy signatures in astrophysics. A central question is whether unresolved millisecond pulsars could account for the signal.
Constraining plausible MSP populations therefore becomes a bridge between compact-object studies in globular clusters and source populations in the Galactic bulge.
Magnetars and long-period transients
Magnetars push neutron-star magnetic fields to the extreme. I am especially interested in the recently discovered ultra-long-period magnetars, also called long-period transients, and what they may reveal about neutron-star diversity.
These systems sit slightly outside my core MSP work, but they raise many of the same questions about evolution and observability.
From resolved sources to unresolved populations
The Galactic Center excess is a reminder that compact-object work often lives at the boundary between individual detections and population inference. That tension is part of what keeps the problem compelling.
Methods and tools
My workflow typically combines Chandra data analysis, population-level interpretation, cross-mission context, and careful use of community data resources.
