Disentangling geometry & growth in cosmic neutrino mass constraints: a more physical split and diagnostic
Fei Ge, Frank J. Qu, Hanyue Wang +3
Recent cosmological data hint at a neutrino mass sum below the minimum value allowed by the neutrino mass oscillation experiments, with a preference for the opposite of massive neu…
Model-Independent Measurement of Baryon Gas Fractions through Galaxy-Galaxy Lensing and the Kinematic Sunyaev-Zel'dovich Effect
R. Henry Liu, Uroš Seljak, Simone Ferraro +52
Baryon feedback is a leading source of systematic uncertainty for cosmology from weak lensing, but measurements of the gas distribution around galaxies have largely relied on param…
The Atacama Cosmology Telescope: Constraints on the anisotropic screening and birefringence effects with DR6
Darby M. Kramer, Alexander van Engelen, Frank J. Qu +14
While we have learned much from recent surveys of the mm-wave sky, many secondary anisotropies of the CMB remain under-explored. We consider two of these here: the anisotropic scre…
Characterising the epoch of reionisation using the cross-correlation of the kSZ effect and CMB lensing
Niall MacCrann, Christopher Cain, Aleksandra Kusiak +5
We investigate the cross-correlation of the kinematic Sunyaev-Zeldovich (kSZ) effect with lensing of the cosmic microwave background (CMB) as a probe of the epoch of reionisation.…
Measuring Cosmic Neutrino Masses Independently of Dark Energy
Frank J. Qu, Fei Ge, Hanyue Wang +4
Neutrino oscillations establish that neutrinos are massive, providing the only laboratory detection of physics beyond the Standard Model. Direct kinematic experiments bound the ele…
Constraints on Cosmic Strings from the Curl-Mode CMB Lensing Power Spectrum measured by ACT DR6
A. I. Lonappan, K. Ramesh, T. Namikawa +2
A network of cosmic strings is one of the few well-motivated cosmological sources of vector and tensor metric perturbations on the largest observable scales. Such perturbations imp…
The Atacama Cosmology Telescope: Probing new signatures of ultralight axions with gravitational lensing
Alex Laguë, Keir K. Rogers, Mathew S. Madhavacheril +14
Ultralight axions (ULAs) are well-motivated dark matter particle candidates that arise in many extensions of the Standard Model of particle physics. ULAs with mass $m_\mathrm{a} \l…
Precision Kinematic Sunyaev--Zel'dovich Measurements Across Halo Mass and Redshift with DESI DR2 and ACT DR6: Part I. Luminous Red Galaxies
F. J. Qu, B. Ried Guachalla, E. Schaan +51
We present the most precise measurements of the kinetic Sunyaev-Zel'dovich (kSZ) effect around luminous red galaxies to date, detecting the signal at significance in both har…
