The Atacama Cosmology Telescope: DR6 Power Spectra, Likelihoods and $Λ$CDM Parameters

Kavli Affiliate: Kent Irwin | Summary:We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Telescope (ACT) data. These cover 19,000 deg$^2$ of sky in bands centered at 98, 150 and 220 GHz, with white noise levels three times […]

SN 2023ixf in the Pinwheel Galaxy M101: From Shock Breakout to the Nebular Phase

Kavli Affiliate: Paul Brink| First 5 Authors: Weikang Zheng, Weikang Zheng, , , | Summary:We present photometric and spectroscopic observations of SN 2023ixf covering from day one to 442 days after explosion. SN 2023ixf reached a peak $V$-band absolute magnitude of $-18.2 pm 0.07$, and light curves show that it is in the fast-decliner (IIL) […]
