A 3D-Printed Millimeter-Wave Inline Waveguide-to-Coplanar-Waveguide Transition to Enable Dense Spectrometer Arrays for Intensity Mapping Surveys

Austin Stover, Juliang Li, Peter Sharpe +4

We present a 3D-printed millimeter-wave, octave-bandwidth, in-line waveguide-to-coplanar-waveguide transition designed to enable focal planes with dense arrays of on-chip spectrome…

Forecasting the cross correlation of Terahertz Intensity Mapper [CII] line intensity maps with Euclid galaxies

Justin S. Bracks, Ryan P. Keenan, Shubh Agrawal +24

We forecast that the Terahertz Intensity Mapper (TIM) cross-correlated with Euclid's Fornax deep field (EDF-F), TIMEDF-F, will detect the [CII]-galaxy cross-power spectrum…

A New Window into the Baryon Cycle at Cosmic Noon with Line Intensity Mapping: Forecasts for auto- and cross-correlations in [CII]-158m, HI 21 cm, CO, and H galaxies

Shubh Agrawal, James E. Aguirre, Justin S. Bracks +24

Across the peak of cosmic star formation at , inflow, processing, and feedback drive rapid changes in the spatial distribution and chemical composition of baryons in gala…

First constraints on causal sources of primordial gravitational waves from BICEP/Keck, SPTpol, SPT-3G, Planck and WMAP -mode data

Jessica A. Zebrowski, Aurora Ireland, Christian L. Reichardt +4

Non-inflationary sources of gravitational waves in the early Universe generically predict causality-limited tensor power spectra at low frequencies. We report the first-ever constr…

Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing

Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143

We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…

Flaring Stars in a Non-targeted mm-wave Survey with SPT-3G

C. Tandoi, S. Guns, A. Foster +96

We present a flare star catalog from four years of non-targeted millimeter-wave survey data from the South Pole Telescope (SPT). The data were taken with the SPT-3G camera and cove…
