A NICER view of PSR J16142230: a massive and compact millisecond pulsar
Lucien Mauviard, Sebastien Guillot, Lami Suleiman +17
Using pulse profile modeling, we obtain the mass-radius measurement of a millisecond pulsar (MSP) with data from the Neutron Star Interior Composition ExploreR, XMM-Newton and the…
Investigating the Mass of the Black Hole and Possible Wind Outflow of the Accretion Disk in the Tidal Disruption Event AT2021ehb
Xin Xiang, Jon M. Miller, Abderahmen Zoghbi +11
Tidal disruption events (TDEs) can potentially probe low-mass black holes in host galaxies that might not adhere to bulge or stellar-dispersion relationships. At least initially, T…
Constraining the magnetic field geometry of the millisecond pulsar PSR~J0030+0451 from joint radio, thermal X-ray and -ray emission
J. Pétri, S. Guillot, L. Guillemot +13
With the advent of multi-wavelength electromagnetic observations of neutron stars, spanning many decades in photon energies, from radio wavelengths up to X-rays and -rays, it be…
NICER X-ray Observations of Seven Nearby Rotation-Powered Millisecond Pulsars
S. Guillot, M. Kerr, P. S. Ray +18
NICER observed several rotation-powered millisecond pulsars to search for or confirm the presence of X-ray pulsations. When broad and sine-like, these pulsations may indicate therm…
Understanding the environment around the intermediate mass black hole candidate ESO 243-49 HLX-1
N. A. Webb, A. Guérou, B. Ciambur +12
Aims. ESO 243-49 HLX-1, otherwise known as HLX-1, is an intermediate mass black hole (IMBH) candidate located 8" (3.7 Kpc) from the centre of the edge-on S0 galaxy ESO 243-49. How…
A likely decade-long sustained tidal disruption event
Dacheng Lin, James Guillochon, S. Komossa +11
Multiwavelength flares from tidal disruption and accretion of stars can be used to find and study otherwise dormant massive black holes in galactic nuclei. Previous well-monitored…
Implications of the delayed 2013 outburst of the ESO 243-49 HLX-1
O. Godet, J. Lombardi, F. Antonini +4
After showing four outbursts spaced by year from 2009 to 2012, the hyper luminous X-ray source ESO 243-49 HLX-1, currently the best intermediate mass black hole (IMBH) can…
Optical variability of the accretion disk around the intermediate mass black hole ESO 243-49 HLX-1 during the 2012 outburst
N. A. Webb, O. Godet, K. Wiersema +5
We present dedicated quasi-simultaneous X-ray (Swift) and optical (Very Large Telescope (VLT), V- and R-band) observations of the intermediate mass black hole candidate ESO 243-49…
Investigating slim disk solutions for HLX-1 in ESO 243-49
O. Godet, B. Plazolles, T. Kawaguchi +7
The hyper luminous X-ray source HLX-1 in the galaxy ESO 243-49, currently the best intermediate mass black hole candidate, displays spectral transitions similar to those observed i…
Pulsed Gamma Rays from the Original Millisecond and Black Widow Pulsars: a case for Caustic Radio Emission?
L. Guillemot, T. J. Johnson, C. Venter +25
We report the detection of pulsed gamma-ray emission from the fast millisecond pulsars (MSPs) B1937+21 (also known as J1939+2134) and B1957+20 (J1959+2048) using 18 months of surve…
A Young Massive Stellar Population Around the Intermediate Mass Black Hole ESO 243-49 HLX-1
S. Farrell, M. Servillat, J. Pforr +9
We present Hubble Space Telescope and simultaneous Swift X-ray telescope observations of the strongest candidate intermediate mass black hole ESO 243-49 HLX-1. Fitting the spectral…
The origin of variability of the intermediate-mass black-hole ULX system HLX-1 in ESO 243-49
J. -P. Lasota, T. Alexander, G. Dubus +5
The ultra-luminous intermediate-mass black-hole system HLX-1 in the ESO 243-49 galaxy exhibits variability with a possible recurrence time of a few hundred days. Finding the origin…
Exploring the Nature of the Brightest Hyper-luminous X-ray Source
Sean Farrell, Mathieu Servillat, Klaas Wiersema +7
The small subset of hyper-luminous X-ray sources with luminosities in excess of ~1E41 erg/s are hard to explain without the presence of an intermediate mass black hole, as signific…
