A first look at the protoplanet WISPIT 2 b with VLTI/GRAVITY+

GRAVITY+ Collaboration, K. Abd El Dayem, R. Abuter +116

Confirmed observations of young protoplanets actively undergoing the process of formation have remained rare to date. In this Letter, we present new insights into the nature of the…

An upper limit on Galactic OB+black hole binaries from SDSS-V

J. Müller-Horn, H. -W. Rix, S. Shahaf +14

Binaries composed of a luminous OB star and a black hole (BH) are a key evolutionary link between massive stellar binaries and merging compact-object binaries, but only a handful a…

Beyond what's observed: hierarchical inference of Gaia astrometric compact-object binaries

Natsuko Yamaguchi, Kareem El-Badry, Reed Essick +3

Astrometry from the Gaia mission has revealed a large and homogeneous population of binaries containing compact objects, including more than 3000 white dwarf--main sequence (WDMS)…

What You Don't Know Won't Hurt You: Self-Consistent Hierarchical Inference with Unknown Follow-up Selection Strategies

Reed Essick, Amanda M. Farah

Many astronomical surveys prompt follow-up observations, but the decision process through which candidates are selected for follow-up can be difficult to model. This poses a challe…

Wide Jets or Low Rates: Reconciling Short GRB and Gravitational-Wave Neutron Star Merger Rates

Keerthi Kunnumkai, Antonella Palmese, Brendan O'Connor +2

Gravitational wave (GW) and short Gamma Ray Burst (sGRB) observations provide us with complementary views of compact object mergers. The paucity of binary neutron star merger (BNS)…

The maximum mass ratio of hierarchical binary black hole mergers may cause the - correlation

Aditya Vijaykumar, Amanda M. Farah, Maya Fishbach

Regardless of their initial spins, the merger of two roughly equal mass black holes (BHs) produces a remnant BH of dimensionless spin . Such remnants can merge with other BHs…

The steep redshift evolution of the hierarchical binary black hole merger rate may cause the - correlation

Amanda M. Farah, Aditya Vijaykumar, Maya Fishbach

There is growing evidence from gravitational-wave observations that some merging black holes are created from previous mergers. Using the prediction that these hierarchically merge…

Evidence of the pair instability gap from black hole masses

Hui Tong, Maya Fishbach, Eric Thrane +13

Stellar theory predicts a forbidden range of black-hole masses between -- due to pair-instability supernovae, but evidence for such a gap in the mass distri…

Gravitational lensing rarely produces high-mass outliers to the compact binary population

Amanda M. Farah, Jose María Ezquiaga, Maya Fishbach +1

All gravitational-wave signals are inevitably gravitationally lensed by intervening matter as they propagate through the Universe. When a gravitational-wave signal is magnified, it…

GWPopulation: Hardware agnostic population inference for compact binaries and beyond

Colm Talbot, Amanda Farah, Shanika Galaudage +2

Since the first direct detection of gravitational waves by the LIGO--Virgo collaboration in 2015, the size of the gravitational-wave transient catalog has grown to nearly 100 event…

Bridging the Gap: Categorizing Gravitational-Wave Events at the Transition Between Neutron Stars and Black Holes

Amanda M. Farah, Maya Fishbach, Reed Essick +2

We search for features in the mass distribution of detected compact binary coalescences which signify the transition between neutron stars and black holes. We analyze all gravitati…

Probing Extremal Gravitational-Wave Events with Coarse-Grained Likelihoods

Reed Essick, Amanda Farah, Shanika Galaudage +4

As catalogs of gravitational-wave transients grow, new records are set for the most extreme systems observed to date. The most massive observed black holes probe the physics of pai…

Counting on Short Gamma-Ray Bursts: Gravitational-Wave Constraints of Jet Geometry

Amanda Farah, Reed Essick, Zoheyr Doctor +2

The detection of GW170817 in gravitational waves and gamma rays revealed that short gamma-ray bursts are associated with the merger of neutron-stars. Gamma rays are thought to resu…

Probing Self-interacting Dark Matter with Disk Galaxies in Cluster Environments

Lucas F. Secco, Amanda Farah, Bhuvnesh Jain +3

Self-Interacting Dark Matter (SIDM) has long been proposed as a solution to small scale problems posed by standard Cold Dark Matter (CDM). We use numerical simulations to study the…
