SAGAbg I: A Near-Unity Mass Loading Factor in Low-Mass Galaxies via their Low-Redshift Evolution in Stellar Mass, Oxygen Abundance, and Star Formation Rate

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Marla Geha, Yao-Yuan Mao, Mithi A. C. de los Reyes, Risa H. Wechsler | Summary: Measuring the relation between star formation and galactic winds is observationally difficult. In this work we make an indirect measurement of the mass loading factor (the ratio between mass […]

Small-scale radio jets and tidal disruption events: A theory of high-luminosity compact symmetric objects

Kavli Affiliate: Roger D. Blandford | First 5 Authors: Andrew G. Sullivan, Roger D. Blandford, Mitchell C. Begelman, Mark Birkinshaw, Anthony C. S. Readhead | Summary: Double lobe radio sources associated with active galactic nuclei represent one of the longest studied groups in radio astronomy. A particular sub-group of double radio sources comprises the compact […]

Small-scale radio jets and tidal disruption events: A theory of high-luminosity compact symmetric objects

Kavli Affiliate: Roger Blandford | Summary:Double lobe radio sources associated with active galactic nuclei represent one of the longest studied groups in radio astronomy. A particular sub-group of double radio sources comprises the compact symmetric objects (CSOs). CSOs are distinguished by their prominent double structure and sub-kpc total size. It has been argued that the […]

Flaring Stars in a Non-targeted mm-wave Survey with SPT-3G

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: , , , , | Summary: We present a flare star catalog from four years of non-targeted millimeter-wave survey data from the South Pole Telescope (SPT). The data were taken with the SPT-3G camera and cover a 1500-square-degree region of the sky from $20^h40^m0^s$ to $3^h20^m0^s$ in […]

Forecasts for Galaxy Formation and Dark Matter Constraints from Dwarf Galaxy Surveys

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Vera Gluscevic, Trey Driskell, Risa H. Wechsler, Leonidas A. Moustakas | Summary: The abundance of faint dwarf galaxies is determined by the underlying population of low-mass dark matter (DM) halos and the efficiency of galaxy formation in these systems. Here, we quantify potential […]

Polarization Leakage and the IXPE PSF

Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Roger W. Romani, , , | Summary: By measuring photoelectron tracks, the gas pixel detectors of the Imaging X-ray Polarimetry Explorer satellite provide estimates of the photon detection location and its electric vector position angle (EVPA). However, imperfections in reconstructing event positions blur […]
