  Stellar rotation is a fundamental observable that drives different aspects of
stellar and planetary evolution. In this work, we present an unprecedented
manifold analysis of 160 B-type stars with light curves collected by the TESS
space mission using three different procedures (Fast Fourier Transform,
Lomb-Scargle, and wavelet techniques), accompanied by rigorous visual
inspection in the search for rotation periodicities. This effort provides
rotational periodicities for 6 new TESS B-type stars and confirmed
periodicities for 22 targets with rotation periods previously listed in the
literature. For other 61 stars, already classified as possible rotational
variables, we identify noisy, pulsational, binarity, or ambiguous variability
behavior rather than rotation signatures. The total sample of 28 potential
rotators shows an overlap of different classes of rotational variables,
composed of $\alpha^2$ Canum Venaticorum, rotating ellipsoidal and SX Arietis
stars. The combination of the three techniques applied in our analysis offers a
solid path to overcome the challenges in the discrimination of rotation from
other variabilities in stellar light curves, such as pulsation, binarity or
other effects that have no physical meaning. Finally, the rotational
periodicities reported in the present study may represent important constraints
for improving stellar evolution models with rotation, as well as asteroseismic
studies of hot stars.
