abstract
We report new measurements of millimeter-wave power spectra in the angular multipole range $2000 \le \ell \le 11,000$ (angular scales $5^\prime \gtrsim \theta \gtrsim 1^\prime$). By adding 95 and 150\,GHz data from the low-noise 500 deg$^2$ SPTpol survey to the SPT-SZ three-frequency 2540 deg$^2$ survey, we substantially reduce the uncertainties in these bands. These power spectra include contributions from the primary cosmic microwave background, cosmic infrared background, radio galaxies, and thermal and kinematic Sunyaev-Zel'dovich (SZ) effects. The data favor a thermal SZ (tSZ) power at 143\,GHz of $D^{\rm tSZ}_{3000} = 3.42 \pm 0.54~ \mu {\rm K}^2$ and a kinematic SZ (kSZ) power of $D^{\rm kSZ}_{3000} = 3.0 \pm 1.0~ \mu {\rm K}^2$. This is the first measurement of kSZ power at $\ge 3\,\sigma$. We study the implications of the measured kSZ power for the epoch of reionization, finding the duration of reionization to be $\Delta z_{re} = 1.0^{+1.6}_{-0.7}$ ($\Delta z_{re}< 4.1$ at 95% confidence), when combined with our previously published tSZ bispectrum measurement.

Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at $z\approx5.6$ with the 21-cm forest power spectrum
A null detection of the 21-cm forest toward quasar J352–15 at z≈5.8 disfavors very cold and substantially neutral intergalactic gas, giving the first observational constraints from a 21-cm forest power spectrum.

Characterising the epoch of reionisation using the cross-correlation of the kSZ effect and CMB lensing
The kSZ-squared field cross-correlated with CMB lensing is a new observable that, in simulations, is sensitive to the duration and midpoint of reionisation and could be detected by a CMB-HD-like experiment.

SPT-3G D1: A Measurement of Secondary Cosmic Microwave Background Anisotropy Power
SPT-3G's 2019–2020 spectra at ell=1700–11000 give D_tSZ=4.91±0.37 μK^2 and D_kSZ=1.75±0.86 μK^2 at ell=3000 (free-CIB model) and a 95% limit Δz_re<3.8 on the reionization duration.

Probing the ionizing photon output of galaxies near cosmic dawn with the patchy kSZ effect
In calibrated reionization simulations, the patchy kSZ power at ell~3000 correlates strongly with the start of reionization once the end is fixed by Lyman-alpha forest data, yielding model-dependent limits on early io...
