    Abstract Based on all 2 minute cadence TESS light curves from Sector 1 to 60, we provide a catalog of 8651 solar-like oscillators, including frequency at maximum power ( ν max , with its median precision σ = 5.39%), large frequency separation (Δ ν , σ = 6.22%), and seismically derived masses, radii, and surface gravity values. In this sample, we have detected 2173 new oscillators and added 4373 new Δ ν measurements. Our seismic parameters are consistent with those from Kepler, K2, and previous TESS data. The median fractional residual in ν max is 1.63%, with a scatter of 14.75%, and in Δ ν it is 0.11%, with a scatter of 10.76%. We have detected 476 solar-like oscillators with ν max exceeding the Nyquist frequency of Kepler long-cadence data during the evolutionary phases of subgiants and the base of the red giant branch, which provide a valuable resource for understanding angular momentum transport.
