The launch of the Imaging X-ray Polarimetry Explorer (IXPE) on 2021 December 9 has opened a new window in X-ray astronomy. We report here the results of the first IXPE observation…
Mapping the circumnuclear regions of the Circinus galaxy with the Imaging X-ray Polarimetry Explorer
F. Ursini, A. Marinucci, G. Matt +94
We report on the Imaging X-ray Polarimetry Explorer (IXPE) observation of the closest and X-ray brightest Compton-thick active galactic nucleus (AGN), the Circinus galaxy. We find…
Direct measurement of decimeter-sized rocky material in the Oort cloud
Denis Vida, Peter G. Brown, Hadrien A. R. Devillepoix +10
The Oort cloud is thought to be a reservoir of icy planetesimals and the source of long-period comets (LPCs) implanted from the outer Solar System during the time of giant planet f…
The First Flight of the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
Sabrina L. Savage, Amy R. Winebarger, Ken Kobayashi +34
The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) sounding rocket experiment launched on July 30, 2021 from the White Sands Missile Range in New Mexico. MaGIXS is a unique…
Temporal and Spectral Evolution of Gamma-ray Burst Broad Pulses: Identification of High Latitude Emission in the Prompt Emission
Donggeun Tak, Z. Lucas Uhm, Judith Racusin +5
We perform a detailed analysis on broad pulses in bright Gamma-ray bursts (GRBs) to understand the evolution of GRB broad pulses. Using the temporal and spectral properties, we tes…
The Birth of a Relativistic Jet Following the Disruption of a Star by a Cosmological Black Hole
Dheeraj R. Pasham, Matteo Lucchini, Tanmoy Laskar +63
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boos…
X-ray Polarization Observations of BL Lacertae
Riccardo Middei, Ioannis Liodakis, Matteo Perri +143
Blazars are a class of jet-dominated active galactic nuclei with a typical double-humped spectral energy distribution. It is of common consensus the Synchrotron emission to be resp…
Dominance of Bursty over Steady Heating of the 4--8 MK Coronal Plasma in a Solar Active Region: Quantification using Maps of Minimum, Maximum, and Average Brightness
Sanjiv K. Tiwari, Lucy A. Wilkerson, Navdeep K. Panesar +2
A challenge in characterizing active region (AR) coronal heating is in separating transient (bursty) loop heating from the diffuse background (steady) heating. We present a method…
Chandra measurements of gas homogeneity and turbulence at intermediate radii in the Perseus Cluster
Martijn de Vries, Adam B. Mantz, Steven W. Allen +6
We present a Chandra study of surface brightness fluctuations in the diffuse intracluster medium of the Perseus Cluster. Our study utilizes deep, archival imaging of the cluster co…
Fermi Gamma-ray Space Telescope
David J. Thompson, Colleen A. Wilson-Hodge
The Fermi Gamma-ray Space Telescope, a key mission in multiwavelength and multimessenger studies, has been surveying the gamma-ray sky from its low-Earth orbit since 2008. Its two…
Template bank for compact binary mergers in the fourth observing run of Advanced LIGO, Advanced Virgo, and KAGRA
Shio Sakon, Leo Tsukada, Heather Fong +34
Matched-filtering gravitational wave search pipelines identify gravitational wave signals by computing correlations, i.e., signal-to-noise ratios, between gravitational wave detect…
Inconspicuous Solar Polar Coronal X-ray Jets as the Source of Conspicuous Hinode/EUV Imaging Spectrometer (EIS) Doppler Outflows
Alphonse C. Sterling, Conrad Schwanitz, Louise K. Harra +3
We examine in greater detail five events previously identified as being sources of strong transient coronal outflows in a solar polar region in Hinode/EUV Imaging Spectrometer (EIS…
Observations of 4U 1626-67 with the Imaging X-ray Polarimetry Explorer
Herman L. Marshall, Mason Ng, Daniele Rogantini +91
We present measurements of the polarization of X-rays in the 2-8 keV band from the pulsar in the ultracompact low mass X-ray binary 4U1626-67 using data from the Imaging X-ray Pola…
(Slow-)Twisting inflationary attractors
Perseas Christodoulidis, Robert Rosati
We explore in detail the dynamics of multi-field inflationary models. We first revisit the two-field case and rederive the coordinate independent expression for the attractor solut…
