Debate Erupts Over How ‘Forbidden’ Black Holes Grow

Quanta Magazine  online

2020-11-03

Smaller black holes might grow to middleweight by guzzling gas and dust. Or they might inflate by consuming one another, enlarging with each successive merger. “Whether one of these processes is relevant, or both, is unclear,” said Imre Bartos, a physicist at the University of Florida. The genesis of intermediate-size black holes matters because it intersects with a number of other astrophysical plotlines.

UF researchers discover new type of black hole

“This black hole teaches us about the universe in ways that we weren’t previously aware of,” said Imre Bartos, an assistant professor at the University of Florida, who chairs the LIGO working group that is searching for intermediate mass black holes.

A Black Hole Collided With Something That Shouldn't Exist

Gizmodo  online

2020-06-23

“This discovery is shocking because we found an object with a mass we did not expect,” explained Imre Bartos, an astrophysicist at the University of Florida and a co-author of the new study, in an email to Gizmodo. This range of compact objects, between about 2.2 and 5 solar masses, was “thought to be uninhabited until now,” he said, in reference to an enigmatic weight class known as the mass gap.

UF physics professors debunk broom social media trend

The Independent Florida Alligator  online

Imre Bartos, an assistant physics professor at UF, credits the reason people can balance their brooms to a concept called “center of mass.” He said brooms can stand by themselves because their center of mass is located at the bottom, toward its bristles.

Two neutron stars collided near the solar system billions of years ago

EurekAlert!  online

2019-05-02

Astrophysicists Szabolcs Marka at Columbia University and Imre Bartos at the University of Florida, have identified a violent collision of two neutron stars 4.6 billion years ago as the likely source of some of the most coveted matter on Earth.

Observation of Gravitational Waves from Two Neutron Star–Black Hole Coalescences

The Astrophysical Journal Letters

R. Abbott, et al.

2021-06-29

We report the observation of gravitational waves from two compact binary coalescences in LIGO's and Virgo's third observing run with properties consistent with neutron star–black hole (NSBH) binaries. The two events are named GW200105_162426 and GW200115_042309, abbreviated as GW200105 and GW200115; the first was observed by LIGO Livingston and Virgo and the second by all three LIGO–Virgo detectors.

Constraints on Cosmic Strings Using Data from the Third Advanced LIGO–Virgo Observing Run

Physical Review Letters

R. Abbott, et al.

2021-06-16

We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection.

Tests of general relativity with binary black holes from the second LIGO-Virgo gravitational-wave transient catalog

Physical Review D

R. Abbott, et al.

2021-06-15

Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the consistency of the data with predictions from the theory. We first establish that residuals from the best-fit waveform are consistent with detector noise, and that the low- and high-frequency parts of the signals are in agreement.

GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo during the First Half of the Third Observing Run

Physical Review X

R. Abbott, et al.

2021-06-09

We report on gravitational-wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between 1 April 2019 15∶00 UTC and 1 October 2019 15∶00 UTC. By imposing a false-alarm-rate threshold of two per year in each of the four search pipelines that constitute our search, we present 39 candidate gravitational-wave events.
