VideoSEAL: Mitigating Evidence Misalignment in Agentic Long Video Understanding by Decoupling Answer Authority
Chenhao Qiu, Yechao Zhang, Xin Luo +2
Long video question answering requires locating sparse, time-scattered visual evidence within highly redundant content. Although current MLLMs perform well on short videos, long vi…
Cross-correlation between the thermal Sunyaev-Zeldovich effect and the Integrated Sachs-Wolfe effect
Ayodeji Ibitoye, Wei-Ming Dai, Yin-Zhe Ma +5
We present a joint cosmological analysis of the power spectra measurement of the Planck Compton parameter and the integrated Sachs-Wolfe (ISW) maps. We detect the statistical corre…
CoLFI: Cosmological Likelihood-free Inference with Neural Density Estimators
Guo-Jian Wang, Cheng Cheng, Yin-Zhe Ma +3
In previous works, we proposed to estimate cosmological parameters with the artificial neural network (ANN) and the mixture density network (MDN). In this work, we propose an impro…
Reconstruction of an Observationally Constrained gravity model
Anirudh Pradhan, Gopikant Goswami, Aroonkumar Beesham
In this paper, an attempt is made to construct a Friedmann-Lemaitre-Robertson-Walker model in gravity with a perfect fluid that yields acceleration at late times. We take…
A non-singular bouncing cosmology in gravity
J. K. Singh, Shaily, Akanksha Singh +2
We investigate a bounce realization in the framework of higher order curvature in modified theory of gravity. We perform a detailed analysis of the cosmological paramete…
The Reconstruction of Constant Jerk Parameter with Gravity
Anirudh Pradhan, Gopikant Goswami, Aroonkumar Beesham
In this work, we have developed an FLRW type model of a universe which displays transition from deceleration in the past to the acceleration at the present. For this, we have consi…
Modeling Transit Dark Energy in -gravity
Anirudh Pradhan, Dinesh Chandra Maurya, Gopikant K. Goswami +1
This research paper deals with a transit dark energy cosmological model in -gravity with observational constraints. For this, we consider a flat FLRW space-time and ha…
LRS Bianchi I model with bulk viscosity in f(R,T) gravity
S. Jokweni, Vijay Singh, Aroonkumar Beesham
Locally-rotationally-symmetric Bianchi type-I viscous and non -viscous cosmological models are explored in general relativity (GR) and in f(R,T) gravity. Solutions are obtained by…
An exact solution of the observable universe in Bianchi V space-time
Rajendra Prasad, Manvinder Singh, Anil Kumar Yadav +1
In this paper we investigate an observable universe in Bianchi type V space-time by taking into account the cosmological constant as the source of energy. We have performed a $χ^{2…
Plane symmetric model in gravity
Vijay Singh, Aroonkumar Beesham
A plane symmetric Bianchi-I model is explored in gravity, where is the Ricci scalar and is the trace of energy-momentum tensor. The solutions are obtained with the…
LRS Bianchi I model with constant expansion rate in gravity
Vijay Singh, Aroonkumar Beesham
An LRS Bianchi-I space-time model is studied with constant Hubble parameter in gravity. Although a single (primary) matter source is considered, an additional matter…
New shear-free relativistic models with heat flow
A. M. Msomi, K. S. Govinder, S. D. Maharaj
We study shear-free spherically symmetric relativistic models with heat flow. Our analysis is based on Lie's theory of extended groups applied to the governing field equations. In…
Lie symmetries for equations in conformal geometries
S. Hansraj, S. D. Maharaj, A. M. Msomi +1
We seek exact solutions to the Einstein field equations which arise when two spacetime geometries are conformally related. Whilst this is a simple method to generate new solutions…
