SAURON's Challenge for the Major Merger Scenario of Elliptical Galaxy Formation

, 2007
The intrinsic anisotropy delta and flattening epsilon of simulated merger remnants is compared with elliptical galaxies that have been observed by the SAURON collaboration, and that were analysed using axisymmetric Schwarzschild models.

Mergers and the outside-in formation of dwarf spheroidals [PDF]

, 2015
We use a cosmological simulation of the formation of the Local Group to explore the origin of age and metallicity gradients in dwarf spheroidal galaxies. We find that a number of simulated dwarfs form "outside-in", with an old, metal-poor population that

Electromagnetic Signals Following Stellar-mass Black Hole Mergers

The Astrophysical Journal Letters, 2017
Abstract It is often assumed that gravitational-wave (GW) events resulting from the merger of stellar-mass black holes are unlikely to produce electromagnetic (EM) counterparts. We point out that the progenitor binary has probably shed a mass ≳10 M ⊙ during its prior evolution.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Signatures of Massive Black Hole Merger Host Galaxies from Cosmological Simulations. II. Unique Stellar Kinematics in Integral Field Unit Spectroscopy

The Astrophysical Journal
Secure methods for identifying the host galaxies of individual massive black hole (MBH) binaries and mergers detected by gravitational-wave experiments such as the Laser Interferometer Space Antenna and pulsar timing arrays are currently lacking, but ...

The inner structure of very massive elliptical galaxies: implications for the inside-out formation mechanism of z~2 galaxies [PDF]

, 2010
We analyze a sample of 23 supermassive elliptical galaxies (central velocity dispersion larger than 330 km s-1), drawn from the SDSS. For each object, we estimate the dynamical mass from the light profile and central velocity dispersion, and compare it ...

Real‐World Pediatric Blinatumomab Administration: Access to Outpatient Care Delivery and Impact of a Hospital‐Dispensed Model

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.

Galaxy evolution in the post-merger regime. IV - The long-term effect of mergers on galactic stellar mass growth and distribution

The Open Journal of Astrophysics
Galaxy mergers are known to trigger bursts of central star formation, which should therefore lead to stellar mass growth in their inner regions. However, observational measurements of this `burst mass fraction' are scant.

Gravitational waves from intermediate-mass black holes in young clusters [PDF]

, 2010
Massive young clusters (YCs) are expected to host intermediate-mass black holes (IMBHs) born via runaway collapse. These IMBHs are likely in binaries and can undergo mergers with other compact objects, such as stellar mass black holes (BHs) and neutron ...

G5.89: an explosive outflow powered by a proto-stellar merger? [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2019
ABSTRACTThe explosive outflows are a newly discovered family of molecular outflows associated with high-mass star-forming regions. Such energetic events are possibly powered by the release of gravitational energy related with the formation of a (proto)stellar merger or a close stellar binary.
