We demonstrate the unprecedented capabilities of the Event Horizon Telescope (EHT) to image the innermost dark matter profile in the vicinity of the supermassive black hole at the center of the M87 radio galaxy. We present the first model of the synchrotron emission induced by dark matter annihilations from a spiky profile in the close vicinity of a supermassive black hole, accounting for strong gravitational lensing effects. Our results show that the EHT should readily resolve dark matter…

Strong Limits on Dark Matter Annihilation from the Event Horizon Telescope Observations of M87$^\star$

The fast developments of radio astronomy open a new window to explore the properties of Dark Matter (DM). The recent direct imaging of the supermassive black hole (SMBH) at the center of M87 radio

Extreme dark matter tests with extreme mass ratio inspirals

Future space-based laser interferometry experiments such as LISA are expected to detect $\cal O$(100--1000) stellar-mass compact objects (e.g., black holes, neutron stars) falling into massive black

Spacetime Metrics and Ringdown Waveforms for Galactic Black Holes Surrounded by a Dark Matter Spike

Theoretical models suggest the existence of a dark matter spike surrounding the supermassive black holes at the core of galaxies. The spike density is thought to obey a power law that starts at a few

Radio constraints on dark matter annihilation in Canes Venatici I with LOFAR†

Dwarf galaxies are dark matter (DM) dominated and therefore promising targets for the search for weakly interacting massive particles (WIMPs), which are well-known candidates for DM. The

New constraints on the dark matter-neutrino and dark matter-photon scattering cross sections from TXS 0506+056

The flux of high energy neutrinos and photons produced in a blazar could get attenuated when they propagate through the dark matter spike around the central black hole and the halo of the host galaxy.

Signatures of leptophilic t -channel dark matter from active galactic nuclei

In this work, we study indirect photon signatures of leptophilic dark matter (DM) coming from Centaurus A, where a DM density spike is believed to have survived to date contrary to the case of our

Ultralight Boson Dark Matter and Event Horizon Telescope Observations of M87^{*}.

A combination of the EHT data and other constraints provides evidence that M87^{*}, the supermassive black hole at the center of the M87 Galaxy, has a mass ∼6.5×10^{9}  M_{⊙}.

Fate of an accretion disc around a black hole when both the viscosity and dark energy is in effect

This paper deals with the viscous accretion flow of a modified Chaplygin gas towards a black hole as the central gravitating object. A modified Chaplygin gas is a particular type of dark energy model

Dynamical constraints on a dark matter spike at the Galactic centre from stellar orbits

In this work I use astrometric and spectroscopic data on the S2 star at the Galactic centre (GC) up to 2016 to derive specific constraints on the size of a dark matter (DM) spike around the central

Deflection of light by rotating regular black holes using the Gauss-Bonnet theorem

In this paper, we study the weak gravitational lensing in the spacetime of rotating regular black hole geometries such as Ayon-Beato-Garc\'ia (ABG), Bardeen, and Hayward black holes. We calculate the



Black holes

The observational evidence for black holes is reviewed, some recent developments involving cosmic censorship and the statistical origin of black hole entropy are described, and some of their properties are described.

General Relativity and Gravitation

A circuit is provided for developing a television synchronization signal and an automatic gain control (AGC) signal which performs the dual functions of tracking the sync signal of the composite video signal and preventing lockout of the keyed AGC circuit.
