A Pair of Early- and Late-Forming Galaxy Cluster Samples: a Novel Way of Studying Halo Assembly Bias Assisted by a Constrained Simulation
Yen-Ting Lin, Hironao Miyatake, Hong Guo +4
The halo assembly bias, a phenomenon referring to dependencies of the large-scale bias of a dark matter halo other than its mass, is a fundamental property of the standard cosmolog…
The thermal and gravitational energy densities in the large-scale structure of the Universe
Yi-Kuan Chiang, Ryu Makiya, Eiichiro Komatsu +1
As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized. We therefore expect a connection between the me…
The Cosmic Thermal History Probed by Sunyaev-Zeldovich Effect Tomography
Yi-Kuan Chiang, Ryu Makiya, Brice Ménard +1
The cosmic thermal history, quantified by the evolution of the mean thermal energy density in the universe, is driven by the growth of structures as baryons get shock heated in col…
Broadband Intensity Tomography: Spectral Tagging of the Cosmic UV Background
Yi-Kuan Chiang, Brice Ménard, David Schiminovich
Cosmic photons can be efficiently collected by broadband intensity mapping but information on their emission redshift and frequency is largely lost. We introduce a technique to sta…
Surveying Galaxy Proto-clusters in Emission: A Large-scale Structure at z=2.44 and the Outlook for HETDEX
Yi-Kuan Chiang, Roderik A. Overzier, Karl Gebhardt +12
Galaxy proto-clusters at z >~ 2 provide a direct probe of the rapid mass assembly and galaxy growth of present day massive clusters. Because of the need of precise galaxy redshifts…
Planck 2013 results. XXIX. The Planck catalogue of Sunyaev-Zeldovich sources: Addendum
Planck Collaboration, P. A. R. Ade, N. Aghanim +276
We update the all-sky Planck catalogue of 1227 clusters and cluster candidates (PSZ1) published in March 2013, derived from Sunyaev-Zeldovich (SZ) effect detections using the first…
Discovery of a large number of candidate proto-clusters traced by ~15 Mpc-scale galaxy overdensities in COSMOS
Yi-Kuan Chiang, Roderik Overzier, Karl Gebhardt
To demonstrate the feasibility of studying the epoch of massive galaxy cluster formation in a more systematic manner using current and future galaxy surveys, we report the discover…
Searching for large-scale structures around high-redshift radio galaxies with Herschel
E. E. Rigby, N. A. Hatch, H. J. A. Röttgering +15
This paper presents the first results of a far-infrared search for protocluster-associated galaxy overdensities using the SPIRE instrument on-board the {\it Herschel} Space Observa…
Ancient Light from Young Cosmic Cities: Physical and Observational Signatures of Galaxy Proto-Clusters
Yi-Kuan Chiang, Roderik Overzier, Karl Gebhardt
For a complete picture of galaxy cluster formation, it is important that we start probing the early epoch of z~2-7 during which clusters and their galaxies first began to form. Bec…
