Lasting mEMRIs: Signatures of Multiple Black Hole Extreme Mass Ratio Inspirals from AGN discs
Encounters of stellar-mass black holes (sBH) in active galactic nuclei discs naturally form mean-motion resonances of sBH pairs.The deepest X-ray view of a kiloparsec scale jet at z=6.1
The mechanism responsible for the high-energy emission observed in kiloparsec-scale jets across cosmic time remains poorly understood.Charting the Galactic Underworld II: Strategies for Identifying BHs and NSs with LISA
Stellar-mass black holes (BHs) and neutron stars (NSs) observed by space-based gravitational-wave detectors offer constraints on binary stellar evolution that are complementary to those from ground-…Gone Without a Bang: A Search for Failed Core-Collapse Supernovae in ZTF and Predictions for Rubin and Roman
The core-collapse of massive stars (${\geq}10\ \rm M_\odot$) usually takes the form of a supernova, but in some cases may lead to a direct collapse, leading to a failed core-collapse supernova…The black hole-galaxy correlations of the 12 micron local AGN sample: a NuSTAR perspective
The M-sigma correlation of inactive galaxies plays a crucial role in estimating the black hole mass (MBH) in active galactic nuclei (AGN): 1) it is used to calibrate the reverberation mapping (RM)…Nuclear Millimeter Continuum Emission in Radio-Quiet Active Galactic Nuclei: an ALMA Spectral and Variability Study
Unresolved millimeter (mm) emission is observed in radio-quiet (RQ) Active Galactic Nuclei (AGN), but its physical origin remains debated.Pulsar J1909+0749 and Supernova Remnant G42.1-0.2: A case of a pulsar that has exited the shell of its associated supernova remnant
(Abridged) The ATNF pulsar catalogue features only 63 pulsars that are possibly associated with a supernova remnant (SNR).The accretion flow and jet of M87: broadband modelling across spatial scales
The nearby radio galaxy M87 is an ideal laboratory for studying accretion flows and relativistic jet emission.PSR~B0355+54: An Unexpected Compendium of Nearly All Scintillation Arc Morphologies
Scintillation arcs are sensitive probes of multipath propagation, offering a window into the distribution of scattering material in the interstellar medium.Optical and Ultraviolet Emission from the Gas Photoionized by Gaia BH3: Archival Constraints and Predictions for the 2029 Periastron
Gaia BH3, a $32.7\,M_\odot$ black hole (BH) on an 11.6-yr, $e=0.73$ orbit around a metal-poor giant at $\approx590$ pc, accretes from its wind.Balmer breaks in accreting super-massive black hole binaries
We show that truncated circumbinary accretion disks around super-massive black hole binaries can produce Balmer breaks.Core-Collapse Supernova Rates in the Dark Energy Survey
Over its five-year campaign (2013-2017), the Dark Energy Survey (DES) supernova (SN) survey recorded 31,636 light curves.Spiraling into the `snail' cluster MCXC J0157.4-0550
We present a deep Chandra (130 ks) study of a striking, tidally induced cold front in a subcluster merging with the galaxy cluster MCXC J0157.4-0550.Clumpy Outflows from Super-Eddington Accreting Black Holes. II. Conditions for Clump Formation
Active galactic nuclei (AGNs) commonly exhibit ultra-fast outflows (UFOs) with velocities of $0.03$--$0.3~c$.Supermassive Black Hole Winds in X-rays -- SUBWAYS. VI. Interplay between the soft X-ray excess and ultra-fast outflows
We present a broadband, multiwavelength study of the interplay between the soft X-ray excess (SE), ultra-fast outflows (UFOs), and warm absorbers (WAs) in 21 active galactic nuclei (AGN; 0.1 <= z <=…$\texttt{GASTRO-BH}$: Effects of a Central Black Hole in GSE-like Dwarf-galaxy Mergers Around Milky Way-like Hosts
Recent evidence points to an intermediate-mass black hole (IMBH) in the most massive globular cluster of the Milky Way, $ω$ Centauri.Gamma-ray calorimetry of Seyfert winds
Two stacking analyses with the Fermi Large Area Telescope (LAT) detected GeV emission from radio-quiet Seyferts, one selected by an X-ray ultra-fast outflow (UFO) and one hard-X-ray-bright, with…Seeing Through the RFI Mask: DT-FISTA Inpainting of Pulsar Dynamic Spectra via Fourier Sparsity
Radio frequency interference (RFI) frequently contaminates radio observations, and excising affected samples leaves masked regions in sampled images.A blazar is a blazar is a blazar ... Comparing long-term varaibility properties of PKS 1510-089 and PKS 2155-304
Blazars are typically divided by spectral appearance; may that be strength of optical emission lines or the frequency of the synchrotron peak.Exploring Cosmic Rays from Gravity-Limited Acceleration at Supermassive Black Holes
We show that horizon-scale magnetic fields around supermassive black holes (SMBHs), only limited by gravity, yield a universal, model-independent ceiling on electromagnetic energy density.
