Gravity Group Lunch Seminar | Yilun Guan (Pittsburgh) & Brandon Hensley (Princeton) "The ACT View of the Galactic Center" Fri, May 7, 2021, 12:00 pm – 12:00 pm We present new maps of the Galactic Center in total intensity and polarization made with the Atacama Cosmology Telescope (ACT). We combine dedicated, arcminute-resolution ACT observations over a 32 deg^2 field with Planck intensity and polarization data at similar frequencies to produce maps with fidelity on both small and large angular scales… Gravity Group Seminar | Zach Atkins, "Map-based Noise Simulations for ACT Data" Suren Gourapura, "r Error Budget for SPIDER's First Flight" Fri, Apr 30, 2021, 12:00 pm – 12:00 pm Zachary Atkins, Princeton University "Map-based Noise Simulations for ACT Data" The next analysis of ACT data will use precision-cosmology-capable maps of the microwave sky based on data taken by the Advanced ACT detector arrays since 2017. The maps will cover the full Advanced ACT footprint (~44% f_sky, see Aiola et al. 2020 and Mallaby… Gravity Group Lunch Seminar | Sarah Marie Bruno, "The projected impact of commercial satellite constellations on ground-based astronomy" & Roman Kolevatov, "The DMRadio Experiment at Princeton" Fri, Apr 23, 2021, 12:00 pm – 12:00 pm Sarah Marie Bruno, Princeton University "The projected impact of commercial satellite constellations on ground-based astronomy" The ongoing commercialization of satellite technology is leading to the ubiquity of privately owned and operated satellite spacecraft in low-Earth orbits. These satellites can be used for… Gravity Group Seminar | Xue (Sherry) Song, Joseph van der List, and Corwin Shiu, PU "B-mode Constraint from SPIDER's First Flight" Fri, Apr 9, 2021, 12:00 pm – 12:00 pm SPIDER is a balloon-borne telescope designed to map the B-mode polarization of the cosmic microwave background (CMB) on degree angular scales. SPIDER’s 2015 flight mapped 4.8% of the sky at 95 and 150 GHz. In this talk, we report the results of internal consistency tests performed on the data to control against instrumental systematics, and… Gravity Group Lunch Seminar | Oliver Philcox, PU "Have we exhausted the galaxy two-point function?" Fri, Apr 2, 2021, 12:00 pm – 12:00 pm Throughout the past three decades, the analysis of spectroscopic surveys has focussed around the two-point function of the galaxy overdensity field, masquerading either as the correlation function or the Fourier-space power spectrum. Today, theoretical interest has shifted towards other statistics, in particular the higher-point functions. Does… By Year 2022 (1)2021 (5)(selected)2020 (10)2019 (15)2018 (13)2017 (24)2016 (30)2015 (27)2014 (20)2012 (14)2011 (5)2010 (2) By Category Astroparticle SeminarAtomic Physics SeminarBiophysics SeminarCondensed Matter SeminarDark Cosmo SeminarDistinguished Lecture SeriesDonald R.
