Detrending Changes the Temporal Dynamics of a Semantic Fluency Task
Frontiers in Aging Neuroscience, 2016 Objective: To study the dynamics of clustering semantic fluency responses and switching between clusters. Methods: We conducted a cross-sectional study of participants (N=60) in a study of patient reported outcomes who were given the Saint Louis ...

Deep Synoptic Array Science: Two Fast Radio Burst Sources in Massive Galaxy Clusters
The Astrophysical Journal Letters, 2023 The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/submillimeter wavelengths (Sunyaev–Zel’dovich effect) for decades.

Gas Stripping of Dwarf Galaxies in Clusters of Galaxies [PDF]
, 2000 Many clusters of galaxies contain an appreciable amount of hot gas, the intracluster medium. As a consequence, gas will be stripped from galaxies that move through the inter cluster medium, if the ram pressure exceeds the internal gravitational force. We

Multiscale analysis of turbulence evolution in the density-stratified intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The diffuse hot medium inside clusters of galaxies typically exhibits turbulent motions whose amplitude increases with radius, as revealed by cosmological hydrodynamical simulations. However, its physical origin remains unclear. It could either be due to

Broad Band Optical Polarimetric Study of IC 1805 [PDF]
, 2007 We present the BVR broad band polarimetric observations of 51 stars belonging to the young open cluster IC 1805. Along with the photometric data from the literature we have modeled and subtracted the foreground dust contribution from the maximum ...

Generation of internal waves by buoyant bubbles in galaxy clusters and heating of intracluster medium [PDF]
, 2018 Buoyant bubbles of relativistic plasma in cluster cores plausibly play a key role in conveying the energy from a supermassive black hole to the intracluster medium (ICM) - the process known as radio-mode AGN feedback.

Universe, 2022 The presence of dust in the intracluster medium (ICM) has been a long-standing problem that is still awaiting elucidation. Direct observational diagnostics are rather challenging (though not impossible) either because of a sparse distribution of dust in ...

Suppression of AGN-driven Turbulence by Magnetic Fields in a Magnetohydrodynamic Model of the Intracluster Medium [PDF]
, 2018 We investigate the role of active galactic nucleus (AGN) feedback in turbulent heating of galaxy clusters. Specifically, we analyze the production of turbulence by g-modes generated by the supersonic expansion and buoyant rise of AGN-driven bubbles ...

Rescuing the intracluster medium of NGC 5813
, 2016 We use recent X-ray observations of the intracluster medium (ICM) of the galaxy group NGC 5813 to confront theoretical studies of ICM thermal evolution with the newly derived ICM properties. We argue that the ICM of the cooling flow galaxy group NGC 5813
