Neural network based emulation of galaxy power spectrum covariances -- A reanalysis of BOSS DR12 data
Joseph Adamo, Hung-Jin Huang, Tim Eifler
We train neural networks to quickly generate redshift-space galaxy power spectrum covariances from a given parameter set (cosmology and galaxy bias). This covariance emulator utili…
Constraining Baryonic Physics with DES Y1 and Planck data -- Combining Galaxy Clustering, Weak Lensing, and CMB Lensing
Jiachuan Xu, Tim Eifler, Vivian Miranda +6
We constrain cosmology and baryonic feedback scenarios with a joint analysis of weak lensing, galaxy clustering, cosmic microwave background (CMB) lensing, and their cross-correlat…
Kinematic Lensing Inference I: Characterizing Shape Noise with Simulated Analyses
Pranjal R. S., Elisabeth Krause, Hung-Jin Huang +4
The unknown intrinsic shape of source galaxies is one of the largest uncertainties of weak gravitational lensing (WL). It results in the so-called shape noise at the level of $σ_ε^…
Kinematic Lensing with the Roman Space Telescope
Jiachuan Xu, Tim Eifler, Eric Huff +4
Kinematic lensing (KL) is a new cosmological measurement technique that combines traditional weak lensing (WL) shape measurements of disc galaxies with their kinematic information.…
Galaxy Morphological Classification with Efficient Vision Transformer
Joshua Yao-Yu Lin, Song-Mao Liao, Hung-Jin Huang +2
Quantifying the morphology of galaxies has been an important task in astrophysics to understand the formation and evolution of galaxies. In recent years, the data size has been dra…
Cosmology from Clustering, Cosmic Shear, CMB Lensing, and Cross Correlations: Combining Rubin Observatory and Simons Observatory
Xiao Fang, Tim Eifler, Emmanuel Schaan +3
In the near future, the overlap of the Rubin Observatory Legacy Survey of Space and Time (LSST) and the Simons Observatory (SO) will present an ideal opportunity for joint cosmolog…
Mitigating baryonic effects with a theoretical error covariance
Maria G. Moreira, Felipe Andrade-Oliveira, Xiao Fang +5
One of the primary sources of uncertainties in modeling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for Stage-IV surveys r…
Dark Energy Survey Year 1 Results: Constraining Baryonic Physics in the Universe
Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum +74
Measurements of large-scale structure are interpreted using theoretical predictions for the matter distribution, including potential impacts of baryonic physics. We constrain the f…
Cosmology with the Wide-Field Infrared Survey Telescope -- Multi-Probe Strategies
Tim Eifler, Hironao Miyatake, Elisabeth Krause +25
We simulate the scientific performance of the Wide-Field Infrared Survey Telescope (WFIRST) High Latitude Survey (HLS) on dark energy and modified gravity. The 1.6 year HLS Referen…
Cosmology with the Wide-Field Infrared Survey Telescope -- Synergies with the Rubin Observatory Legacy Survey of Space and Time
Tim Eifler, Melanie Simet, Elisabeth Krause +27
We explore synergies between the space-based Wide-Field Infrared Survey Telescope (WFIRST) and the ground-based Rubin Observatory Legacy Survey of Space and Time (LSST). In particu…
Modeling baryonic physics in future weak lensing surveys
Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum +1
Modifications of the matter power spectrum due to baryonic physics are one of the major theoretical uncertainties in cosmological weak lensing measurements. Developing robust mitig…
An Analysis Framework for Understanding the Origin of Nuclear Activity in Low-Power Radio Galaxies
Yen-Ting Lin, Hung-Jin Huang, Yen-Chi Chen
Using large samples containing nearly active galaxies of low radio luminosity (1.4 GHz luminosity between and W/Hz, essentially low-excit…
Intrinsic Alignment in redMaPPer clusters -- II. Radial alignment of satellites toward cluster centers
Hung-Jin Huang, Rachel Mandelbaum, Peter E. Freeman +3
We study the orientations of satellite galaxies in redMaPPer clusters constructed from the Sloan Digital Sky Survey at to determine whether there is any preferential t…
Intrinsic alignments in redMaPPer clusters -- I. Central galaxy alignments and angular segregation of satellites
Hung-Jin Huang, Rachel Mandelbaum, Peter E. Freeman +4
The shapes of cluster central galaxies are not randomly oriented, but rather exhibit coherent alignments with the shapes of their parent clusters as well as with the surrounding la…
On Detecting Halo Assembly Bias with Galaxy Populations
Yen-Ting Lin, Rachel Mandelbaum, Yun-Hsin Huang +5
The fact that the clustering of dark matter halos depends not only on their mass, but also the formation epoch, is a prominent, albeit subtle, feature of the cold dark matter struc…
Stellar Mass Assembly of Brightest Cluster Galaxies at Late Times
Takahiro Inagaki, Yen-Ting Lin, Hung-Jin Huang +2
Understanding the formation history of brightest cluster galaxies is an important topic in galaxy formation. Utilizing the Planck Sunyaev-Zel'dovich cluster catalog, and applying t…
