Query: Investigating the Constraints on Primordial Features with Future Cosmic
  Microwave Background and Galaxy Surveys   In this article, we do a thorough investigation of the competency of the
forthcoming Cosmic Microwave Background (CMB) and Galaxy surveys in probing the
features in the primordial power spectrum. Primordial features are specific
model-dependent corrections on top of the standard power-law inflationary power
spectrum; the functional form being given by different inflationary scenarios.
Signature of any significant departure from the feature-less power spectrum
will enable us to decipher the intricacies of the inflationary Universe. Here,
we delve into three major yet distinct features, namely, Bump feature, Sharp
feature signal, and Resonance feature signal. To analyse the features, we adopt
a specific template for each feature model. We estimate the possible
constraints on the feature parameters by employing Fisher matrix forecast
analysis for the upcoming CMB missions such as CMB-S4, CORE-M5, LiteBIRD, PICO
conjointly with DESI, and EUCLID galaxy surveys. To this end, we make use of
four distinct observations to forecast on the bounds on the model parameters,
namely, CMB, Baryon Acoustic Oscillations (BAO), Galaxy Clustering and
Gravitational Weak Lensing or Cosmic Shear and their permissible synergy. For
large scale structure (LSS) information, we consider different upper limits of
scale for different redshifts for the purpose of circumventing the propagation
of the errors stemming from the uncertainties on nonlinear scales into the
constraints on the feature parameters. A comparative analysis of all three
features has been done to estimate relative capabilities of these upcoming
observations in shedding light on this crucial aspect of precision cosmology.
