A Global Overview of Starobinsky Inflation beyond slow-roll with CMB-BAO data
Tarun, Tanmoy Modak, Björn Malte Schäfer
We perform a global analysis of the Starobinsky inflation using most recent CMB data from ACT and SPT together with DESI BAO measurements. By directly solving the equations of moti…
Nonminimal couplings and preheating effects in -Higgs inflation after ACT and SPT data
Haneesh Gonuguntla, Tanmoy Modak, Arnab Samanta
We study the effects of dimension-four and dimension-six nonminimal Higgs couplings to the Ricci scalar in the -Higgs inflation model in light of the recent ACT and SPT ob…
Baryogenesis in -Higgs Inflation: the Gravitational Connection
Yann Cado, Christoph Englert, Tanmoy Modak +1
-Higgs inflation stands out as one of the best-fit models of Planck data. Using a covariant formalism for the inflationary dynamics and the production of helical gauge fields,…
Cornering Extended Starobinsky Inflation with CMB and SKA
Tanmoy Modak, Lennart Röver, Björn Malte Schäfer +2
Starobinsky inflation is an attractive, fundamental model to explain the Planck measurements, and its higher-order extension may allow us to probe quantum gravity effects. We show…
Probing the Inflaton Potential with SKA
Tanmoy Modak, Tilman Plehn, Lennart Röver +1
SKA will be a major step forward not only in astrophysics, but also in precision cosmology. We show how the neutral hydrogen intensity map can be combined with the Planck measureme…
