We report the discovery of X-ray polarization from the X-ray-bright filament. G0.13-0.11 in the Galactic center (GC) region. This filament features a bright, hard X-ray source that…
Dark Sage: Next-generation semi-analytic galaxy evolution with multidimensional structure and minimal free parameters
Adam R. H. Stevens, Manodeep Sinha, Alexander Rohl +4
After more than five years of development, we present a new version of Dark Sage, a semi-analytic model (SAM) of galaxy formation that breaks the mould for models of its kind. Incl…
LiteBIRD Science Goals and Forecasts. A Case Study of the Origin of Primordial Gravitational Waves using Large-Scale CMB Polarization
P. Campeti, E. Komatsu, C. Baccigalupi +107
We study the possibility of using the satellite -mode survey to constrain models of inflation producing specific features in CMB angular power spectra. We explore a p…
Integral Field Spectroscopy: a disruptive innovation for observations of Planetary Nebulae and the PNLF
Martin M. Roth, George Jacoby, Robin Ciardullo +3
A quarter of a century has passed since the observing technique of integral field spectroscopy (IFS) was first applied to planetary nebulae (PNe). Progress after the early experime…
The ALMA-CRISTAL survey: Widespread dust-obscured star formation in typical star-forming galaxies at z=4-6
Ikki Mitsuhashi, Ken-ichi Tadaki, Ryota Ikeda +29
We present the morphological parameters and global properties of dust-obscured star formation in typical star-forming galaxies at z=4-6. Among 26 galaxies composed of 20 galaxies o…
Exploring the low-mass regime of galaxy-scale strong lensing: Insights into the mass structure of cluster galaxies
Giovanni Granata, Pietro Bergamini, Claudio Grillo +8
We aim at a direct measurement of the compactness of three galaxy-scale lenses in massive clusters, testing the accuracy of the scaling laws that describe the members in strong len…
Minutes-duration Optical Flares with Supernova Luminosities
Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…
