Eccentricity constraints disfavor single-single capture in nuclear star clusters as the origin of all LIGO-Virgo-KAGRA binary black holes
Nihar Gupte, M. Coleman Miller, Rhiannon Udall +12
Multiple formation pathways have been proposed for the origin of binary black holes (BBHs). These include isolated binary evolution and dynamical assembly in dense stellar environm…
Accurate and efficient simulation-based inference for massive black-hole binaries with LISA
Alice Spadaro, Jonathan Gair, Davide Gerosa +7
We develop an accurate simulation-based inference framework for high-mass () black-hole binaries observable by LISA. The method is implemented within th…
Flexible Gravitational-Wave Parameter Estimation with Transformers
Annalena Kofler, Maximilian Dax, Stephen R. Green +6
Gravitational-wave data analysis relies on accurate and efficient methods to extract physical information from noisy detector signals, yet the increasing rate and complexity of obs…
Accelerated inference of microlensed gravitational waves with machine learning
Marienza Caldarola, Srashti Goyal, Nihar Gupte +2
Gravitational waves (GWs) within the LIGO-Virgo-KAGRA sensitivity band can be microlensed by stellar and intermediate-mass black holes, producing a frequency-dependent modulation o…
GW200208_222617 as an eccentric black-hole binary merger: properties and astrophysical implications
Isobel Romero-Shaw, Jakob Stegmann, Hiromichi Tagawa +4
Detecting orbital eccentricity in a stellar-mass black-hole merger would point to a non-isolated formation channel. Eccentric binaries can form in dense stellar environments such a…
Fast and accurate parameter estimation of high-redshift sources with the Einstein Telescope
Filippo Santoliquido, Jacopo Tissino, Ulyana Dupletsa +9
The Einstein Telescope (ET), along with other third-generation gravitational wave (GW) detectors, will be a key instrument for detecting GWs in the coming decades. However, analyzi…
Real-time gravitational-wave inference for binary neutron stars using machine learning
Maximilian Dax, Stephen R. Green, Jonathan Gair +7
Mergers of binary neutron stars (BNSs) emit signals in both the gravitational-wave (GW) and electromagnetic (EM) spectra. Famously, the 2017 multi-messenger observation of GW170817…
Evidence for eccentricity in the population of binary black holes observed by LIGO-Virgo-KAGRA
Nihar Gupte, Antoni Ramos-Buades, Alessandra Buonanno +9
Binary black holes (BBHs) in eccentric orbits produce distinct modulations in gravitational waves (GWs); measuring orbital eccentricity provides evidence for dynamical binary forma…
Utilizing Radiomic Feature Analysis For Automated MRI Keypoint Detection: Enhancing Graph Applications
Sahar Almahfouz Nasser, Shashwat Pathak, Keshav Singhal +5
Graph neural networks (GNNs) present a promising alternative to CNNs and transformers in certain image processing applications due to their parameter-efficiency in modeling spatial…
Reverse Knowledge Distillation: Training a Large Model using a Small One for Retinal Image Matching on Limited Data
Sahar Almahfouz Nasser, Nihar Gupte, Amit Sethi
Retinal image matching plays a crucial role in monitoring disease progression and treatment response. However, datasets with matched keypoints between temporally separated pairs of…
EinsteinPy: A Community Python Package for General Relativity
Shreyas Bapat, Ritwik Saha, Bhavya Bhatt +46
This paper presents EinsteinPy (version 0.3), a community-developed Python package for gravitational and relativistic astrophysics. Python is a free, easy to use a high-level progr…
Optimal Gravitational-wave Follow-up Tiling Strategies Using a Genetic Algorithm
Nihar Gupte, Imre Bartos
The identification of electromagnetic emission from gravitational-wave sources typically requires multiple follow-up observations due to the limited fields-of-view of follow-up obs…
Gravitational-wave follow-up with CTA after the detection of GRBs in the TeV energy domain
Imre Bartos, K. Rainer Corley, Nihar Gupte +3
The recent discovery of TeV emission from gamma-ray bursts (GRBs) by the MAGIC and H.E.S.S. Cherenkov telescopes confirmed that emission from these transients can extend to very hi…
How would a nearby kilonova look on camera?
Nihar Gupte, Imre Bartos
Kilonovae are cosmic optical flashes produced in the aftermath of the merger of two neutron stars. While the typical radiant flux of a kilonova can be as high as \,W, they…
Observational consequences of structured jets from neutron star mergers in the local Universe
Nihar Gupte, Imre Bartos
The recent multi-messenger discovery of binary neutron star (BNS) merger GW170817 showed that -ray emission in short GRBs is wider than the central energetic narrow cone, and we…
