Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, Volume 41, Issue 4, Page 645-659, May 2026.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Bubbles and jets in the center of M51

The Astrophysical Journal, 1985
Optical and radio observations of the nucleus of the galaxy M51 are presented. The observations show that M51 appears to have a bidirectional jet which emanates from the nucleus and interacts with the surrounding interstellar medium. H-alpha + forbidden N II monochromatic photographs and VLA 20 cm and 6 cm radio maps reveal a bright, resolved cloud and

An intermediate‐mass black hole candidate in M51? [PDF]

Astronomische Nachrichten, 2016
AbstractWe present the current results of an investigation into M51 ULX‐7, using archival data from XMM‐Newton, Chandra and NuSTAR, and optical and radio data from HST and VLA. The source has a consistently hard power‐law X‐ray spectrum and high short‐term variability.

From gas to stars along the spiral wave: CO, HCN, and star formation variations across the spiral arms in NGC 4321 and M51

Astronomy & Astrophysics
Context. Molecular clouds form stars from the interstellar medium via gravitational collapse, following a sequence from low-density gas to high-density cores and eventually the formation of stars. In classical density wave theory, gas clouds orbiting the

The Star Cluster Population of M51

, 2004
We present the age and mass distribution of star clusters in M51. The structural parameters are found by fitting cluster evolution models to the spectral energy distribution consisting of 8 HST-WFPC2 pass bands. There is evidence for a burst of cluster formation at the moment of the second encounter with the companion NGC5195 (50-100 Myr ago) and a ...

Fire and Ice in the Whirlpool: Spatially Resolved Scaling Relations between X-Ray-emitting Hot Gas and Cold Molecular Gas in M51

The Astrophysical Journal Letters
The cold and hot interstellar medium in star-forming galaxies resembles the reservoir for star formation and associated heating by stellar winds and explosions during stellar evolution, respectively.

Morphology and Kinematics of the Gas in M51: How Interaction with NGC 5195 Has Molded the Structure of Its Arms

The Astrophysical Journal
The Whirlpool Galaxy is a well-studied grand design galaxy with two major spiral arms, and a large satellite NGC 5195. The arms both show long uniform sections with perturbations (“kinks” or sharp turns) in specific regions.

Tunnel combinations that should be avoided in anterior cruciate ligament reconstruction: a biomechanical assessment of 15 different combinations of femoral and tibial graft tunnels

Bone & Joint Open
Aims: Structured knowledge on the combined effect of various positions of femoral and tibial tunnels in reconstruction of the anterior cruciate ligament (ACL) on knee range of motion, rotatory stability, and anterior translatory laxity is limited.
