Modelling of laboratory data of bi-directional reflectance of regolith surface containing Alumina
C. Bhattacharjee, D. Deb, H. S. Das +2
Bidirectional reflectance of a surface is defined as the ratio of the scattered radiation at the detector to the incident irradiance as a function of geometry. The accurate knowled…
The second data release from the European Pulsar Timing Array: IV. Implications for massive black holes, dark matter and the early Universe
J. Antoniadis, P. Arumugam, S. Arumugam +111
The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and fir…
Comparing recent PTA results on the nanohertz stochastic gravitational wave background
The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…
Quark stars with 2.6 in a non-minimal geometry-matter coupling theory of gravity
G. A. Carvalho, R. Lobato, P. H. R. S. Moraes +2
This work analyses the hydrostatic equilibrium configurations of strange stars in a non-minimal geometry-matter coupling (GMC) theory of gravity. Those stars are made of strange qu…
High performing ionanofluid electrolyte with higher lithium salt concentration for safer lithium metal batteries
P. Bose, D. Deb, S. Bhattacharya
A new class of high-performance pyrrolidinium cation based ionanofluid electrolytes with higher lithium salt concentration are developed. The electrolytes are formed by dispersing…
Study of the charged super-Chandrasekhar limiting mass white dwarfs in the gravity
F. Rocha, G. A. Carvalho, D. Deb +1
The equilibrium configuration of white dwarfs composed of a charged perfect fluid are investigated in the context of the gravity, for which and …
Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
F. Iraci, A. Chalumeau, C. Tiburzi +46
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…
The second data release from the European Pulsar Timing Array V. Search for continuous gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +97
We present the results of a search for continuous gravitational wave signals (CGWs) in the second data release (DR2) of the European Pulsar Timing Array (EPTA) collaboration. The m…
Characteristics of Deterministic and Stochastic Sandpile Models in a Rotational Sandpile Model
S. B. Santra, S. Ranjita Chanu, D. Deb
Rotational constraint representing a local external bias generally has non-trivial effect on the critical behavior of lattice statistical models in equilibrium critical phenomena.…
The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +95
We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar T…
The second data release from the European Pulsar Timing Array II. Customised pulsar noise models for spatially correlated gravitational waves
J. Antoniadis, P. Arumugam, S. Arumugam +95
The nanohertz gravitational wave background (GWB) is expected to be an aggregate signal of an ensemble of gravitational waves emitted predominantly by a large population of coalesc…
