Magnetic field in the Lobes of the Seyfert Galaxy NGC3516: Suggestions of a Helical field

Salmoli Ghosh, P. Kharb, E. Sajjanhar +2

We present polarization images from the Karl G. Jansky Very Large Array (VLA) and the Giant {Metrewave} Radio Telescope (GMRT) at 5.5, 10 GHz and 663 MHz of the changing-look (CL)…

Turbulent dynamos in a collapsing cloud

Muhammed Irshad P, Pallavi Bhat, Kandaswamy Subramanian +1

The amplification of magnetic fields is crucial for understanding the observed magnetization of stars and galaxies. Turbulent dynamo is the primary mechanism responsible for that b…

Understanding the radio luminosity function of star-forming galaxies and its cosmological evolution

Charles Jose, Luke Chamandy, Anvar Shukurov +3

We explore the redshift evolution of the radio luminosity function (RLF) of star-forming galaxies using GALFORM, a semi-analytic model of galaxy formation and a dynamo model of the…

Iterative removal of sources to model the turbulent electromotive force

Abhijit B. Bendre, Jennifer Schober, Prasun Dhang +1

We describe a novel method to compute the components of dynamo tensors from direct magnetohydrodynamic (MHD) simulations. Our method relies upon an extension and generalisation of…

Role of magnetic pressure forces in fluctuation dynamo saturation

Sharanya Sur, Kandaswamy Subramanian

Using magnetohydrodynamic simulations of fluctuation dynamos in turbulent flows with rms Mach numbers and , we show that magnetic pressure for…

Extragalactic magnetism with SOFIA (SALSA Legacy Program) -- V: First results on the magnetic field orientation of galaxies

Alejandro S. Borlaff, Enrique Lopez-Rodriguez, Rainer Beck +13

We present the analysis of the magnetic field (-field) structure of galaxies measured with far-infrared (FIR) and radio (3 and 6 cm) polarimetric observations. We use the first…

Remnants of recent mergers in nearby early-type galaxies and their classification

Gourab Giri, Sudhanshu Barway, Somak Raychaudhury

We search for signatures of recent galaxy close interactions and mergers in a sample of 202 early-type galaxies in the local universe from the public SDSS Stripe82 deep images ($μ_…

Dashing through the cluster: An X-ray to radio view of UGC 10420 undergoing ram-pressure stripping

Smriti Mahajan, Kulinder Pal Singh, Juhi Tiwari +1

We present multi-wavelength data and analysis, including new FUV AstroSat/UVIT observations of the spiral galaxy UGC 10420 (z=0.032), a member of the cluster Abell 2199. UGC 10420…
