Periodic Radio and X-ray Emission from an Accreting White Dwarf Binary
Kovi Rose, Joshua Pritchard, Tara Murphy +26
Long period radio transients (LPTs) are coherent bursts of polarised radio emission that repeat periodically on timescales of minutes to hours. Little is known about the physical o…
Lensed Type Ia Supernova "Encore" at z=2: The First Instance of Two Multiply-Imaged Supernovae in the Same Host Galaxy
J. D. R. Pierel, A. B. Newman, S. Dhawan +60
A bright (=24 mag), supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply-imaged as a result o…
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 Galaxy Groups and Clusters in the IllustrisTNG Simulations
Meng Gu, Charlie Conroy, Benedikt Diemer +6
Recent stellar population analysis of early-type galaxy spectra has demonstrated that the low-mass galaxies in cluster centers have high [] and old ages characteristic of…
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…
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…
Low Metallicities and Old Ages for Three Ultra-Diffuse Galaxies in the Coma Cluster
Meng Gu, Charlie Conroy, David Law +17
A large population of ultra-diffuse galaxies (UDGs) was recently discovered in the Coma cluster. Here we present optical spectra of three such UDGs, DF7, DF44 and DF17, which have…
A Novel Approach to Constrain the Mass Ratio of Minor Mergers in Elliptical Galaxies: Application to NGC 4889, the Brightest Cluster Galaxy in Coma
Meng Gu, Luis C. Ho, Chien Y. Peng +1
Minor mergers are thought to be important for the build-up and structural evolution of massive elliptical galaxies. In this work, we report the discovery of a system of four shell…
