Nucleon isovector momentum fraction, helicity and transversity moment using Lattice QCD
Santanu Mondal, Tanmoy Bhattacharya, Rajan Gupta +5
We present our recent high precision calculations (Phys. Rev. D102 (2020) no.5, 054512 and JHEP 04 (2021) 044, JHEP 21 (2020) 004) of the first moment of nucleon isovector polarize…
Progress in the determination of Mellin moments of the pion LCDA using the HOPE method
William Detmold, Anthony V. Grebe, Issaku Kanamori +4
The pion light-cone distribution amplitude (LCDA) is a central non-perturbative object of interest for the calculation of high-energy exclusive processes in quantum chromodynamics.…
Low Frequency Quasi Periodic Oscillations and Shocks in Accretion onto Black Hole
Chandra B. Singh, Santanu Mondal, David Garofalo
Low-frequency quasi-periodic oscillations (LFQPOs) have been routinely observed in black hole X-ray binaries (BHXRBs). These LFQPOs can be explained by axisymmetric shock oscillati…
Fermi bubbles: the collimated outburst needed to explain forward-shock edges
Santanu Mondal, Uri Keshet, Kartick C. Sarkar +1
The bipolar, nonthermal, high-latitude lobes known as the Fermi bubbles (FBs) are thought to originate from a massive energy release near the Galactic centre (GC). We constrain the…
Strange and charm contributions to nucleon charges and moments
Rui Zhang, Tanmoy Bhattacharya, Rajan Gupta +4
We present preliminary results for strange and charm contributions to nucleon charges and moments. The scalar, axial and tensor charges, and unpolarized first moments are calculate…
Parton physics from a heavy-quark operator product expansion: Lattice QCD calculation of the second moment of the pion distribution amplitude
William Detmold, Anthony Grebe, Issaku Kanamori +4
The pion light-cone distribution amplitude (LCDA) is a central non-perturbative object of interest for high-energy exclusive processes in quantum chromodynamics. In this article, t…
Spectral signature of mass outflow in Two Component Advective Flow Paradigm
Santanu Mondal, Sandip K. Chakrabarti
Outflows are common in many astrophysical systems. In the Two Component Advective Flow ({\fontfamily{qcr}\selectfont TCAF}) paradigm which is essentially a generalized Bondi flow i…
Emission lines from X-ray illuminated accretion disc in black hole binaries
Santanu Mondal, Tek P. Adhikari, Chandra B. Singh
X-ray flux from the inner hot region around central compact object in a binary system illuminates the upper surface of an accretion disc and it behaves like a corona. This region c…
Changing Accretion Geometry of Seyfert 1 Mrk 335 with {\it NuSTAR}: A Comparative Study
Santanu Mondal, C. S. Stalin
We present a detailed spectral study of the narrow-line Seyfert~1 galaxy, Markarian~335, using eight epoch observations made between 2013 and 2020 with the Nuclear Spectroscopic Te…
Precision Nucleon Charges and Form Factors Using 2+1-flavor Lattice QCD
Sungwoo Park, Rajan Gupta, Boram Yoon +5
We present high statistics results for the isovector nucleon charges and form factors using seven ensembles of 2+1-flavor Wilson-clover fermions. The axial and pseudoscalar form fa…
