Internal Structure, Not Environment, Shapes Metallicity Gradients in Low-Mass Galaxies from MaNGA
Anuroop Dasgupta, Namrata Roy, Saumyadip Samui +2
Dwarf and low-mass galaxies are highly sensitive to stellar feedback and gas flows, yet their spatially resolved gas-phase metallicity remains poorly characterised. We measure radi…
Signature of Bursty Star Formation in the High-Redshift Galaxies Detected with JWST
Rupam Sarkar, Saumyadip Samui
Recent JWST observations reveal an unexpectedly slow evolution in ultraviolet luminosity functions (UV LFs) at redshifts . To investigate this phenomenon, we develop a semi…
Studying Cosmic Dawn using redshifted HI 21-cm signal: A brief review
Ankita Bera, Raghunath Ghara, Atrideb Chatterjee +2
In this review article, we briefly outline our current understanding of the physics associated with the HI 21-cm signal from cosmic dawn. We discuss different phases of cosmic dawn…
Impact of cosmic rays on the global 21-cm signal during cosmic dawn
Ankita Bera, Saumyadip Samui, Kanan K. Datta
It is extremely important to understand the processes through which the thermal state of the inter-galactic medium (IGM) evolved in the early universe in order to study the evoluti…
Exploring the Voids: Luminosity Functions and Magnetic Field
Agniva Roychowdhury, Saumyadip Samui
We present semi-analytical models for magnetisation of the void inter-galactic medium (IGM) by outflows from void galaxies. The number density of dark matter haloes in an under-den…
Primordial magnetic fields during the cosmic dawn in light of EDGES 21-cm signal
Ankita Bera, Kanan K. Datta, Saumyadip Samui
We study prospects of constraining the primordial magnetic field (PMF) and its evolution during the dark ages and cosmic dawn in light of EDGES 21-cm signal. Our analysis has been…
