The MASSIVE SURVEY XVI. The Stellar Initial Mass Function in the Center of MASSIVE Early-Type Galaxies

Meng Gu, Jenny Greene, Andrew B. Newman +4

The stellar initial mass function (IMF) is a fundamental property in the measurement of stellar masses and galaxy star formation histories. In this work we focus on the most massiv…

Coordinated Assembly of Brightest Cluster Galaxies

Meng Gu, Charlie Conroy, Gabriel Brammer

Brightest Cluster Galaxies (BCGs) in massive dark matter halos are shaped by complex merging processes. We present a detailed stellar population analysis in the central region of A…

Hierarchical Galaxy Growth and Scatter in the Stellar Mass - Halo Mass Relation

Meng Gu, Charlie Conroy, Peter Behroozi

The relation between galaxies and dark matter halos reflects the combined effects of many distinct physical processes. Observations indicate that the stellar mass-halo mass (…

A MaNGA about the Legacy I: Connecting the Assembly of Stellar Halo with the Average Star Formation History in Low-Redshift Massive Galaxies

Xiao-Ya Zhang, Song Huang, Meng Gu

We investigate the connection between stellar mass distribution, assembly history, and star formation timescales in low-redshift massive early-type galaxies (ETGs) by combining dee…

The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library

D. S. Aguado, Romina Ahumada, Andres Almeida +230

Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…

Spectroscopic Constraints on the Build-up of the Intracluster Light in the Coma Cluster

Meng Gu, Charlie Conroy, David Law +13

The stellar content of the intracluster light (ICL) provides unique insight into the hierarchical assembly process of galaxy clusters.However, the ICL is difficult to study due to…
