RT-DETR-World: Transferring Rich LLM Semantics to Real-Time Open-Vocabulary Detection

Yupeng Zhang, Ziyi Zhao, Juntao Cheng +4

Open-vocabulary detection (OVD) recognizes categories unseen during training through textual category queries, yet achieving strong generalization with real-time efficiency remains…

Impact of neglecting center-of-mass acceleration in parameter estimation of stellar-mass black holes

Suvikranth Gera, Poulami Dutta Roy

A tertiary body near a coalescing binary can imprint its influence on the gravitational waves (GWs) emitted by that binary in the form of center-of-mass (CoM) acceleration. An exam…

Shadows of generalised Hayward spacetimes : in vacuum and with plasma

Suvikranth Gera, Saurabh Kumar, Poulami Dutta Roy +1

We investigate the shadow properties of a wide class of spacetimes arising from different parameter regimes of the generalized Hayward metric, characterized by two independent para…

Impact of unmodeled eccentricity on the tidal deformability measurement and implications for gravitational wave physics inference

Poulami Dutta Roy, Pankaj Saini

With the expected large number of binary neutron star (BNS) observations through gravitational waves (GWs), third-generation GW detectors, Cosmic Explorer (CE) and Einstein Telesco…

Generalised Hayward spacetimes: Geometry, matter and scalar quasinormal modes

Poulami Dutta Roy, Sayan Kar

Bardeen's 1968 idea of a regular black hole spacetime was revived by Hayward in 2006 through the construction of a new example of such a geometry. Later it was realised by Neves an…
