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 […]
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 […]

Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Erin Kara, Jeroen Homan, James F. Steiner, Diego Altamirano | Summary: IGR J17091-3624 is a black hole X-ray binary (BHXB), often referred to as the ‘twin’ of GRS 1915+105 because it is the only other known BHXB that can show exotic ‘heartbeat’-like variability that is […]
Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Erin Kara, Javier A. García, Diego Altamirano, Tomaso Belloni | Summary: While the standard X-ray variability of black hole X-ray binaries (BHXBs) is stochastic and noisy, there are two known BHXBs that exhibit exotic `heartbeat’-like variability in their light curves: GRS 1915+105 and IGR J17091-3624.

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Maxwell Klein, Keren Sharon, Kate Napier, Michael D. Gladders, Gourav Khullar | Summary: We present a strong lensing analysis of COOL J1241+2219, the brightest known gravitationally lensed galaxy at $z geq 5$, based on new multi-band Hubble Space Telescope (HST) imaging data. The lensed galaxy has […]
Kavli Affiliate: Jing Wang | First 5 Authors: Javira Altmann, Carlota Andres, Anton Andronic, Federico Antinori, Pietro Antonioli | Summary: This paper is a write-up of the ideas that were presented, developed and discussed at the fourth International Workshop on QCD Challenges from pp to AA, which took place in February 2023 in Padua, Italy. […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Matias I. Jones, Yared Reinarz, Rafael Brahm, Marcelo Tala Pinto, Jan Eberhardt | Summary: We report on the confirmation and follow-up characterization of two long-period transiting substellar companions on low-eccentricity orbits around TIC 4672985 and TOI-2529, whose transit events were detected by the TESS space mission. Ground-based […]
