The Atacama Cosmology Telescope: Modeling the Gas Thermodynamics in BOSS CMASS galaxies from Kinematic and Thermal Sunyaev-Zel’dovich Measurements

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Stefania Amodeo, Nicholas Battaglia, Emmanuel Schaan, Simone Ferraro, Emily Moser | Summary: The thermal and kinematic Sunyaev-Zel’dovich effects (tSZ, kSZ) probe the thermodynamic properties of the circumgalactic and intracluster medium (CGM and ICM) of galaxies, groups, and clusters, since they are proportional, respectively, to the integrated […]

Weyl gauge theories of gravity do not predict a second clock effect

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We consider Weyl gauge theories of gravity (WGTs), which are invariant both under local Poincar’e transformations and local changes of scale. Such theories may be interpreted as gauge theories in Minkowski spacetime, but their gravitational interactions are most often […]

Proper pushforwards on finite dimensional adic spaces

Posted by klaurent Tokyo

Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, Christopher Lazda, , , | Summary: For any separated, taut, locally of $^+$weakly finite type morphism $f:Xrightarrow Y$ between finite dimensional, analytic adic spaces, we construct the higher direct images with compact support $mathbf{R}^qf_!mathscr{F}$ of any abelian sheaf $mathscr{F}$ on $X$. The basic approach follows […]

Young Faithful: The Eruptions of EC 53 as It Cycles through Filling and Draining the Inner Disk

Posted by klaurent Peking

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee, Gregory Herczeg, Steve Mairs | Summary: While young stellar objects sometimes undergo bursts of accretion, these bursts usually occur sporadically, making them challenging to study observationally and to explain theoretically. We build a schematic description of cyclical bursts of the young […]
