Isolating Sgr A East: The First Uncontaminated X-ray Maps of a Galactic Center Supernova Remnant
Mayura Balakrishnan, Adrien Picquenot, Lia Corales +3
The central few parsecs of the Milky Way host a complex X-ray-emitting environment in which several extended plasma components are blended along the line of sight, complicating att…
Observations of AGN-driven feedback: dynamics and ionization of the filaments in M87
Camille Poitras, Marie-Lou Gendron-Marsolais, Valeria Olivares +9
We present a comprehensive kinematic and ionization analysis of the warm ionized filaments ( K) in M87, the central galaxy of the Virgo cluster, using new integral field spec…
Direct observation of the X-ray counterpart of the Hα filaments and of the sloshing spiral in the Perseus galaxy cluster
Adrien Picquenot, Fabio Acero, Valeria Olivares +2
Deep Chandra observations of the Perseus galaxy cluster have allowed for the discovery of X-ray counterparts to the Hα filamentary structures and of a sloshing spiral. However, bot…
H-X-ray Surface Brightness Correlation for Filaments in Cooling Flow Clusters
Valeria Olivares, Adrien Picquenot, Yuanyuan Su +4
Massive galaxies in cooling flow clusters display clear evidence of feedback from Active Galactic Nuclei (AGN). Joint X-ray and radio observations have shown that AGN radio jets pu…
Comparing the three-dimensional morphological asymmetries in the ejecta of Kepler and Tycho in X-rays
Adrien Picquenot, Tyler Holland-Ashford, Brian J. Williams
Recent simulations have shown that asymmetries in the ejecta distribution of supernova remnants (SNRs) may be a reflection of asymmetries left over from the initial supernova explo…
Mapping thermal emission in the synchrotron-dominated SNRs 330.2+1.0, 3C58, and RX J1713.7-3946
Adrien Picquenot, Brian J. Williams, Fabio Acero +1
Since the discovery of synchrotron X-ray emission from the shell of the supernova remnant (SNR) SN 1006, multiple observations from Chandra and XMM-Newton have shown that many youn…
Flux Contribution and Geometry of the Charge Exchange Emission in the Starburst Galaxy M82
Hiromichi Okon, Randall K. Smith, Adrien picquenot +1
Recent X-ray studies of starburst galaxies have found that Charge eXchange (CX) commonly occurs between the outflowing hot plasma and cold gas, possibly from swept-up clouds. Howev…
Rapid Expansion of the Young Type Ia Supernova Remnant 0519-69.0: More Evidence for a Circumstellar Shell
Benson T. Guest, Kazimierz J. Borkowski, Parviz Ghavamian +5
The nature of Type Ia supernovae remains controversial. The youngest remnants of Ia supernovae hold clues to the explosion and to the immediate surroundings. We present a third epo…
The X-ray synchrotron rims in Cassiopeia A narrow with energy
Adrien Picquenot, Brian J. Williams, Fabio Acero +1
Some young supernova remnants exhibit thin filaments of X-ray synchrotron radiation coinciding with the forward shock due to accelerated electrons interacting with the local magnet…
Three-dimensional morphological asymmetries in the ejecta of Cassiopeia A using a component separation method in X-rays
Adrien Picquenot, Fabio Acero, Tyler Holland-Ashford +2
Recent simulations have shown that asymmetries in the ejecta distribution of supernova remnants (SNR) can still reflect asymmetries from the initial supernova explosion. Thus, thei…
A novel method for component separation of extended sources in X-ray astronomy
Adrien Picquenot, Fabio Acero, Jérôme Bobin +3
In high-energy astronomy, spectro-imaging instruments such as X-ray detectors allow investigation of the spatial and spectral properties of extended sources including galaxy cluste…
