Candidate high-redshift protoclusters and lensed galaxies in the Planck list of high-z sources overlapping with Herschel-SPIRE imaging

Caleb Lammers, Ryley Hill, Seunghwan Lim +3

The Planck list of high-redshift source candidates (the PHz catalogue) contains 2151 peaks in the cosmic infrared background, unresolved by Planck's 5 arcmin beam. Follow-up spectr…

X-ray spectroscopy of the starburst feedback in 30 Doradus

Yingjie Cheng, Q. Daniel Wang, Seunghwan Lim

X-ray observations provide a potentially powerful tool to study starburst feedback. The analysis and interpretation of such observations remain challenging, however, due to various…

Is there enough star formation in simulated protoclusters?

Seunghwan Lim, Douglas Scott, Arif Babul +5

As progenitors of the most massive objects, protoclusters are key to tracing the evolution and star-formation history of the Universe, and are responsible for per c…

Constraints on circum-galactic media from Sunyaev-Zel'dovich effects and X-ray data

Xuanyi Wu, Houjun Mo, Cheng Li +1

We use observational measurements of thermal and kinetic Sunyaev-Zel'dovich effects, as well as soft X-ray emission associated with galaxy groups to constrain the gas density and t…

Detection of missing baryons in galaxy groups with kinetic Sunyaev-Zel'dovich effect

Seunghwan Lim, H. J. Mo, Huiyuan Wang +1

We present the detection of the kinetic Sunyaev-Zel'dovich effect (kSZE) signals from groups of galaxies as a function of halo mass down to …

Exploring the thermal energy contents of the intergalactic medium with the Sunyaev-Zel'dovich effect

Seunghwan Lim, Houjun Mo, Huiyuan Wang +1

We examine the thermal energy contents of the intergalactic medium (IGM) over three orders of magnitude in both mass density and gas temperature using thermal Sunyaev-Zel'dovich ef…

Gas contents of galaxy groups from thermal Sunyaev-Zel'dovich effects

Seunghwan Lim, Houjun Mo, Ran Li +4

A matched filter technique is applied to the Planck all-sky Compton y-parameter map to measure the thermal Sunyaev-Zel'dovich (tSZ) effect produced by galaxy groups of different ha…

Galaxy groups in the low-redshift Universe

Seunghwan Lim, Houjun Mo, Yi Lu +2

We apply a halo-based group finder to four large redshift surveys, the 2MRS, 6dFGS, SDSS and 2dFGRS, to construct group catalogs in the low-redshift Universe. The group finder is b…

Testing galaxy formation models with galaxy stellar mass functions

Seunghwan Lim, Houjun Mo, Ting-Wen Lan +1

We compare predictions of a number of empirical models and numerical simulations of galaxy formation to the conditional stellar mass functions (CSMF)of galaxies in groups of differ…

An observational proxy of halo assembly time and its correlation with galaxy properties

Seunghwan Lim, Houjun Mo, Huiyuan Wang +1

We show that the ratio between the stellar mass of central galaxy and the mass of its host halo, , can be used as an observable proxy of halo assembly…

The Extended Zel'dovich Mass Functions of Clusters and Isolated Clusters in the Presence of Primordial Non-Gaussianity

Seunghwan Lim, Jounghun Lee

We present new formulae for the mass functions of the clusters and the isolated clusters with non Gaussian initial conditions. For this study, we adopt the Extended Zel'dovich (EZL…

An Extended Zel'dovich Model for the Halo Mass Function

Seunghwan Lim, Jounghun Lee

A new way to construct a fitting formula for the halo mass function is presented. Our formula is expressed as a solution to the modified Jedamzik matrix equation that automatically…

An Analytic Formula for the Supercluster Mass Function

Seunghwan Lim, Jounghun Lee

We present an analytic formula for the supercluster mass function which is constructed by modifying the extended Zel'dovich model for the halo mass function. The formula has two ch…
